Saying goodbye to a beloved TV character is always hard. But next week's farewell to Cory Monteith's Finn Hudson on "Glee" promises to be one of the most tear-filled farewells ever. In a 30-second teaser of "The Quarterback" released on Wednesday, we see the kids of McKinley High paying their respects to Finn in what show runner Ryan Murphy said was an heart-wrenching episode
 that was "incredibly difficult to work on."

Opening with a shot of an empty school hallway, the trailer is set to the mournful strains of Adele's "Make You Feel My Love." We see the student singers solemnly marching down that hallway, each holding a pair of drum sticks with a black ribbon on them as well as a box with Finn's helmet, bobblehead and other personal items.

"The hardest word to say," reads the screen, "is goodbye," over a shot of the gang putting a football down in the middle of a flower and candle-strewn tribute to Finn outside his locker. "Finn, you are a star that left too soon. But we will always look up to find you," reads a note from Zach Brooke.

"The episode is called 'The Quarterback,' and Cory really was that to that group of people and to me particularly," Murphy reporters after wrapping work on the next week's episode on Thursday. "That group of kids particularly went through the limelight and became world famous at a very difficult age, and many of them really struggled with it ... Cory obviously very much struggled with it, but never on the ...

Ever wonder why a busy movie star like Anthony Mackie — who has seven movies coming out in 2013 alone — signs on to a project? If that project is "Runner, Runner," which opens Friday (October 4), the answer is simple: to slap the sh-- out of Justin Timberlake.

"You know it's funny, I told Justin, he and Ben [Affleck] are probably the luckiest guys on Earth," Mackie told MTV News' Josh Horowitz about his "Runner, Runner" co-stars. "They both have beautiful, amazing wives — rich wives. They both cannot lose. He puts out an album, it goes platinum. Ben wins a poker championship. He wins Oscars. He directs movies. So I just told Justin, I want to bring you down to Earth a little bit. Just smack you up. So that's why I took it. None of that was in the script, I just went on set and slapped the sh-- out of him."

In case you're wondering, that wasn't exactly part of the plan. In the movie, Mackie plays Agent Shavers, an FBI agent who tries to use Timberlake's Richie Furst to bring down an online poker kingpin played by Ben Affleck. So technically Shavers is supposed to become friends with Furst, but as Mackie explains, that's not exactly how things turned out:

"Nope. Nope. I went to the director, said I have a different idea about this character. I just go around smacking people. 'Eh-hoo!' Bop. Shut up."

You're just going to have to watch the video to get the full effect of Mackie's Justin Timberlake impersonation, because text ...

There's a reason director James Cameron has gone on record calling the "best space film ever done": It's visually stunning.

It took nearly five years to bring Alfonso Cuaron's vision to the big-screen, and nearly every second of the film had to be painstakingly planned and choreographed with director of photography Emmanuel Lubezki before Cuaron ever yelled "action!"

"Well, we had to pre-visualize the whole film before we started shooting — in a very precise way," Cuaron told MTV News. "It was not only pre-visualization, but also pre-lighting it. We have to light it virtually because then everything on set was pre-programmed."

While the entire film will no doubt be eye candy for any cinephile, preview audiences have been particularly abuzz over the jaw-dropping destruction in the film's initial moments that set the scene for the rest of those 90 minutes.

"The whole idea of that opening scene was to create the reality that you're accustomed to seeing in an IMAX documentary, and Chivo Lubezki was particularly concerned about the quality of the light," Cuaron explained. "The light in space is unlike anything we experience on Earth, because it is completely unfiltered. And the other thing was to create that reality in those documentaries — those are one single shot. You don't have intercuts or stuff. We want to represent a space mission almost with all its finality before disaster strikes, and then the camera, from being objective becomes the point of view of the camera, and from that point on, the camera is a third character that is the ...

Every superhero movie is only as good as the supervillain it unleashes. Thankfully for Marvel, Tom Hiddleston's charming portrayal of Loki in 2011's "Marvel's the Avengers" has been embraced by an incredibly passionate fanbase. In addition to creating Internet memes based on Loki's hair and fanfic pairing him up with pretty much every character in the Marvel Cinematic Universe, Hiddleston's fans have gone so far as to create a Change.org petition with more than 25,000 signatures demanding a solo film for the character.

But however much love Loki's followers have for the guy who caused the destruction of a sizable chunk of Manhattan in "The Avengers," none of those 25,000 fans understand Loki as well as the man responsible for playing him on the big screen.

"You can't sit in judgment," Hiddleston explained to MTV News during our "Thor: The Dark World" set visit. "So in my own mind, I've unpacked his suitcase of pain. I can easily stand up and defend him even though many of his actions are indefensible... So yeah, I do like him. I was also enormously charming."

Fans got to see that charm ramped up in "The Avengers," the film that saw Loki bury all of the familial strife that defined his character arc in "Thor." Hiddleston credited "Avengers" writer and director Joss Whedon for giving Loki's ego a bit of a boost while on set.

"What I love about playing him is that there's a delight [in him] now because of the way the character was developed by ...

Miley Cyrus drops plenty of knowledge in her MTV doc, — "You're always going to make people talk. You might as well make them talk for two weeks, rather than two seconds" is a particular favorite — though for all her straight talk, she does say some things that might have left you scratching your head.

They're called "Mileyisms," and if they've got you confused, don't feel bad: Not everyone is fluent in Cyrus-ese. Luckily, we are (we took a couple classes in college), and to add enjoyment to your future viewings of "The Movement," we've compiled a handy list of some of Miley's favorite phrases. Because how else are you supposed to tell the difference between a "Biew Biew" and a "Giant Adult Baby?"

» "Bad Bitch" Miley considers herself one, though it took cutting off all her hair to realize her true B.B. potential. Total amount of f---s given must not exceed 0.

» "Bean, Mary Jane, Floyd" These are the names of Miley's dogs. She speaks to them as if they are human beings. One of them gets very freaked out while Cyrus is playing the Bangerz track "FU."

» "Biew Biew" Miley's nickname for her assistant/BFF Cheyne, who was working at a Starbucks before being hired by Cyrus. Most folks find him very handsome.

» "Doctor Things" We're not really sure what they are, though we do learn that Miley "paid, like, $2,000" for them.

» "Dope" A state of being Miley continually strives to attain. "Nothing can have my face on it, my name on it, that isn't ...

People "can't stop" talking about Miley Cyrus's twerk-y performance at the 2013 Video Music Awards, but when it comes to Cyrus, she has her own perspective:

"The best thing I've done in my career is 'We Can't Stop' music video," Cyrus says in an unlocked clip from the upcoming deluxe edition of "Miley: The Movement." "It was like spontaneous. It was all really real. No one was there that were just actors pretending to be my friends."

Fans successfully unlocked on Thursday (October 3) an exclusive clip from the deluxe version of the documentary, which airs Sunday, Oct 6 at 8 p.m. ET. From now until Sunday, fans can tweet #UnlockMiley to unearth even more clips from the doc, which will be available via the MTV app.

In theclip, Cyrus spills on the Diane Martel-directed music video, in which she — to refresh your memory — dances with bears, trucks with french fry skulls and, naturally, licks everything in sight.

"People are expecting a shocking video, but it's doing it in a way that's not predictable," she said in the clip. "Yeah, maybe I'm here and being crazy and sticking my tongue out, but I'm dressed as a bear. It's toughness and raunchiness, but with something that's really sweet and endearing. There was these subconscious little trippy moments in there, and that's why people wanted to watch it over and over and over again."

Cyrus's musings on the video are just one of many revealing moments in a documentary that tells the tale of the pop star's reinvention, ...

Mike Will Made It's phone is on fire. Every rapper is calling the Atlanta hitmaker, but after he dropped his Air Jordan-inspired with Miley Cyrus, Wiz Khalifa and Juicy J, Mike Will got a ring from Michael Jordan himself.

"The first day the video came out, he saw the video and he liked it," Mike Will told MTV News on Thursday (October 3). "He was like, 'Man I like the video.' He was like, 'Thanks a lot.' "

The clip finds Mike Will and company taking over a high school gym, smoking in the bathroom and, of course, rocking some pretty sweet (and rare) Air Jordans basketball shoes. Mike Will partnered with Hannah Lux Davis to co-direct the video, which dropped last month.

Miley sports a bikini dress, made from authentic Jordan basketball jerseys and matching sneakers. In various scenes, she treats her feet to a pair of Wolf Grey Air Jordan 5s and Fire Red 3s. Juicy J shows off a pair of Grape Air Jordan 5s and the Olympic-colored Air Jordan 7s, that MJ rocked on his way to winning the gold as a member of the 1992 Dream Team squad.

For Mike Will, getting clean sneaker shots for the video were just as important as giving shine to his "23" collaborators. He was particularly disappointed that the camera didn't catch the fine details on his Defining Moments Air Jordan 11s, a limited edition riff on the pair of patent leather sneakers that Jordan wore in the 1995-1996 season where ...

Pusha T has one hell of an album intro for his upcoming My Name is My Name. On "King Push," the G.O.O.D. Music rhyme dealer makes royal proclamations over an intense sound bed of military drumrolls and eerie synth keys. What makes the track even better is that it was produced by Joaquin Phoenix — or so we thought.

"While it was widely reported that Pusha T used my beat and that I produced his song, I can't take any credit," the quirky actor said in a statement issued to XXLMag.com. "A friend's son played me his music, and all I did was make an introduction to Kanye's camp."

Turns out Phoenix's friend is Metallica drummer Lars Ulrich and his son is the actual producer in question. "This is how I got it: Joaquin Phoenix gave the beat to 'Ye, so when I got the beat from 'Ye, it was, 'Yo, Joaquin gave me this beat.' So I'm just like, OK, I know Joaquin's into music and the whole thing," the Clipse MC explained to Rap-Up. "I believe it is the son, I want to say, of Lars Ulrich from Metallica [who produced 'King Push']. I hope I'm not wrong this time... It was a mistake because it came from Joaquin."

When MTV News caught up with Push in September, he broke down "King Push" for us and confirmed that Phoenix produced the record. It was back in August when Push first revealed that Phoenix was involved with the creation of his debut LP My Name is ...
