Nobody is out to sabotage an entire script and do an improvisational experiment of a movie, but when they're feeling something in the moment, let them make it their own. That's what makes them great actors.

I was trying to get the slightly more cinematic version of my relationship with my mom, which I think was a really common relationship. I adored my mom. I thought she was the best. I loved her very much.

I told my mom I was going to do a movie about a son who hears a story about his mom and takes her on a cross-country road trip, and I wanted to actually take the trip with my mom to see what it would be like to drive cross-country with your mom.

If something good was happening in my life, I'd call my mom to let her know. If something bad was happening, she'd be somebody whose advice I would seek out. We had a very good relationship, but she drove me crazy, all the time. But, she drove me crazy in a loving way.

I couldn't understand her [my mother's] wiring, all the time. I couldn't understand how she denied herself pleasure and enjoyment in life. As my career got successful and I wanted to do things for her, she wasn't able to allow them because she just didn't work that way. It was always that. It wasn't necessarily ugly, just complicated.

A lot of times, when mother-son or mother-daughter relationships have been put on screen, they tend to trickle towards ugly, and I don't find that totally realistic for the wide swath of us and it's also not that fun to watch.

Some of my favorite movies have explored the father-son dynamic, in a very loving way. It can be complicated, but at the end, it's that moment where you're crying because of that core relationship.
