Interviewer: 'There's are many people that are so funny in these movies. Who was the hardest to keep a straight face with?'

Jennifer Lawrence: 'Oh... Oh my God, that's so hard. They both... it's impossible, 'cause they were both absolutely hilarious on and off camera. But on camera, I was saying earlier, that is my greatest, proudest acting moment is not laughing in scenes with Caesar [Stanley Tucci] when he's interviewing me and when he's talking about anything.'
