I want the look of a movie to be secondary. I really want people to be engaged in the story and the characters and not think about a style or think about me or think about the director of photography and what a great job he's doing. I never feel like that should be there.

I thought I could make a sarcastic joke about it. But it's based on my own struggle with how much to give, how much it's really helping or not, and how foolish or not I feel. Giving sometimes backfires.

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 thought of the scene while writing scenes with Rebecca [Hall] and wrote it like an opening montage of showing where someone works. If you see a film about a car mechanic, you'd show the place they work and what they do. So, that's what I set out to do with Rebecca's character. I thought it probably wouldn't even make it into film but I ended up liking it.

I definitely feel like a native New Yorker. My personality was formed there.

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.

I wrote lots of scripts that never got made and they were terrible. I thought they were good at the time. You can't write two scripts and expect your career to take off. Keep writing. Be you. Be original. A lot of people go for a genre, which is fine if you can do that really well, but we all have such layered histories. We all come from a unique background. Write about your past, write about you. Or make stuff up, but make it about something that really matters.
