Quotes

• “My character is the one who says what the audience is thinking, she’s like ‘Wait, what’?”
• “For me, it’s a lot of fun to play the role and it’s a dream to play in a movie like this, a huge, huge epic,” the Philadelphia native said while kicking-back on a couch after filming an intense scene where a small desert town is leveled by massive automaton called the Destroyer. “I feel really lucky to be in this movie.”
• “She’s a fascinating girl and we’ve been friends for a while,” Dennings said. “She didn’t know that I got the role and when I told her she was so excited. We get to spent tons of time together and of course [costar] Stellan Skarsgård, who is in all the same scenes as us, gets so sick of us being so girly all the time, the poor guy. She’s an amazing actress and you she’s got a great head on her shoulders.”
• “She’s kind of like a cute, clueless, little puppy or maybe a hamster,” Dennings said. “There wasn’t much on the page for the Darcy role to begin with and I didn’t even see a script before I took the job so I didn’t really know who Darcy was at first. But she really evolved — she’s so much fun now even. She’s very Scooby-Doo if that makes sense. She’s always three steps behind and reacting to what’s happening with these great expressions. ‘Zoinks.’ She gets things wrong and doesn’t care. And she wears these hats. What could be better?"
• “There is a pretty great female presence in the film with Jane Foster and Darcy and Sif also, and Frigga, Thor’s mother.”
• "I really like, not to be biased, but I really like our relationship in the movie."
• “Darcy makes food for Jane, and mixes her Kashi in the morning and basically she’s a new invention. She’s not in the comics. She just sort of hopes to be like Jane one day.”
• “I’ve read a lot of the comic books just growing up, and I sort of felt, for me anyway, that I should sort of view the script as its own thing and not try to compare and contrast the previous stuff, and just treat it like its own little universe. And Darcy wasn’t in the comics, so I didn’t have to worry about continuity or anything like that.”
• “He’s someone I always idolized for acting. I’ve seen Much Ado About Nothing at least 800,000 times. He’s just so gifted in that there isn’t one moment that wasn’t explained thoroughly. There wasn’t a second, for me at least, that I didn’t completely understand what was going on, because he tells you everything, and he makes sure you’re not feeling lost. I can’t say enough.”
• "I do know the answer to that [if she'll be back for Thor: The Dark World]. However I do not have the clearance to talk...interpret that as you will. I've asked when I can say things, but apparently I can't yet, so that will come soon."
• "I can’t tell you a lot. I don’t know exactly what they’re releasing, so I’m not sure what I’m allowed to say. And if I say the wrong thing, I’m going to probably be assassinated. The experience has been fantastic. I think the atmosphere of this movie is going to feel a lot more authentic for fans. I think that will be really cool."
