Nina Jacobson answer the questions on Quora

• Q: How did Jennifer Lawrence develop as an actress over the four films?
• Nina Jacobson: She was a force of nature from day one in terms of her acting ability. I've seen her develop her voice publicly and learn how to use the platform she has to speak up on subjects that matter to her.
• Q: What's it like to work with Jennifer Lawrence?
• N.J.: Jen is every bit as fun to work with as she seems like she would be. She is not a method actor, which means that she doesn't need to stay in character between takes. She can (and does) go from being a total goofball one minute to delivering a jaw dropping emotional performance the next. Its kind of a freak of nature thing to watch. She's very close with her costars and with Francis so she spends a lot of time just hanging out. She also reads a lot on set (like I do) and is always looking for a good book recommendation.
