Filming is a funny combination of having a good time and not being able to wait until it's over.

I think that sometimes, romantic comedies have to be really broad, and that the plot of people falling in and out of love or whatever is not enough. 'Enough Said' had that stuff, but I wanted it to be fun and funny while also grounded in reality.

I think I'm a good writer. I think I have my own voice, which is unique to everyone - everyone has their own voice; if they would just write from a vulnerable embarrassing place, it's going to be universal, and it's going to be entertaining. Because everyone is the same, and everyone is unique.

What's the trick to writing a great female character? Make her human.

If anything, I learned most from being a huge fan of his and watching movies like Annie Hall and Manhattan over and over again - that influenced the kind of movies that I wanted to make more than anything else.

Hollywood always likes to create a star.

I never get tired of looking at her [Catherine Keener] and it always surprises me, despite how many hours of film I've shot on that face. She's fantastic. She does comedy and tragedy so equally well. She wears her feeling so on the surface for both. I try to stop myself from casting her but I just keep coming back to her. She's just so fantastic to work with.

My grandma has said many of the things her character says. But she was much nicer! I made her meaner for dramatic purposes.

I guess I always knew going into the movie that casting that part would be difficult. Oliver just felt likeable. I felt it would be hard to dislike this man. I don't know why, but I'm sure other directors have felt the same when casting him. Oliver is goofy yet formidable, smart but likeable... I didn't want the character of Alex to be nasty or demonised. I wanted him to be struggling with his actions.

Yeah, people seem to really relate to it and feel moved by it. It's been the most positively received of all my movies so far. I don't know why. I like it just as much as I like my others, but people think this one is the best or the most interesting. I'll take it, though. I wouldn't want them to be saying my films are getting worse.
