"Marnie would drive me crazy if we were friends in real life," Allison told BuzzFeed. "But I have to put that out of my head in order to play her. Like, sleeping with Elijah (Andrew Rannells) is crazy, sleeping with Ray (Alex Karpovsky) is crazy, furiously hitting on Desi (Ebon Moss-Bachrach) when he mentions his girlfriend in their first conversation is crazy; but I have to be on the couch with her and Elijah hoping they fuck, I have to be in that apartment with Ray kinda wanting it to happen, and I have to support her quest for Desi." But the thing Allison's struggled with most was Marnie's decision to sleep with artist Booth Jonathan (Jorma Taccone) in season 2 of Girls. "I was fighting that the whole time as Allison," she says, with a sigh. "I did not want her to go down that road. I thought Marnie was better than that, but she wasn't, so I had to be OK with it too. I had to believe Booth was a genius when I walked out of that TV tower, whereas I, as Allison, couldn't stop thinking, It puts the lotion on its skin." Photo: Getty

Robert Pattinson hates Twilight, hates Edward, and hates how everyone likes both. (P.S. There's even a Tumblr devoted to his interviews where he has to talk about Twilight and ultimately makes fun of it.) Perhaps the best quote: "He's the most ridiculous person ... the more I read the script, the more I hated this guy ... Plus, he's a 108 year-old virgin so he's obviously got some issues there."

Even though Kate doesn't hate Titanic the film, she's not too thrilled with her performance as Rose when looking back. "Every single scene, I'm like 'Really, really? You did it like that? Oh my God ... Even my American accent, I can't listen to it. It's awful," she told the Telegraph. "Hopefully it's so much better now. It sounds terribly self indulgent but actors do tend to be very self-critical. I have a hard time watching any of my performances, but watching Titanic I was just like, 'Oh God, I want to do that again.'" Photo: Getty

It's not that Adam Brody hates the character he played on The O.C., it's that he hates talking about him now. (Understandable.) In an interview with the Huffington Post, the actor got candid about why he's kind of annoyed to keep talking about Seth. "It gets boring, that's all. The only way it bothers me — it's not that I'm not proud of it — it's that I've exhausted the conversations about it, in my mind," Brody said. "Forgive me for comparing myself in any way — and I'm not — but Harrison Ford, I understand why he would be crotchety talking about Star Wars." Photo: Getty

In an interview with Allure, Lively explained that playing such a privileged and troubled character on Gossip Girl was at times "personally compromising." "It's a weird thing when people feel like they know you really well, and they don't," Blake said. "I would not be proud to be the person who gave someone the cocaine that made them overdose and then shot someone and slept with someone else's boyfriend." "People loved it, but it always felt a little personally compromising — you want to be putting a better message out there," she said. "The lines become blurred … It doesn't help when everybody is dating who they're dating on the show, and you're also saying to the costume designer, 'Hey, can I take that home?'" Photo: Getty

As the star of the first two Transformers films, when asked whether she'd star in the third, Fox told Entertainment Weekly, "Sure. I mean, I can't sh-t on this movie because it did give me a career and open all these doors for me. But I don't want to blow smoke up people's ass. People are well aware that this is not a movie about acting. And once you realize that, it becomes almost fun because you can be in the moment and go, 'All right, I know that when he calls Action! I'm either going to be running or screaming, or both.'" She also later called director Michael Bay both misogynistic and a "nightmare," saying that he once had her clean his Ferrari and had her on a skin tanning regimen. Photo: Getty
