And after you've done the acting, there's a lot of places you can put your input - in the editing, in the production of it, in the rewriting of it and so on.
And in that time, I lost my dad and had kids of my own. It was like, OK, I get it now. I know what fatherhood is all about. And you look at your parents differently.
But at the same time that the experience is pulling you apart, it's also bonding you. You have this joint venture! You both made this baby. And that's the thing I still can't get over.
But I really felt that, something about the lights going down, and the sense of community. I saw this movie at one festival, and there were 1700 people.
But the two of them together, broke my heart. Olympia and Peter, those scenes... When they're kissing in their 20s and then kissing in their 70s, that's what it is. And they had never met five minutes before they shot those scenes.
But you get past that and realize you have to let go of what you think you want. There'll be plenty of time for that later. Right now, go and be with that baby. Just play with this beautiful little boy.
Field of Dreams is the only movie - and I saw it in the theater - on an afternoon when I was on location somewhere, and there were like 12 people in the theater. I was just so devastated; I couldn't get out of my seat. And I sat and watched it a second time.
I remember my wife and I used to get on plane and see everybody else with their babies. They'd be putting strollers and car seats up above, and we'd think: Oh, please Lord, don't make us go through that.
I'd distract myself until finally it was a combination of things. The show was over and I had time on my hands. I had taken time and played and just relaxed.
In fact, I had the idea because of Peter Falk. I saw my dad watching a Peter Falk movie and something clicked in my head. I gotta go make a movie for Peter Falk and me.
In the original draft I was 27 and Peter was 55 in the script. That's not the same as a guy in his 40s and a dad in the end of his 70s. It's a different point in both our lives.
It's not like some movies where you're following a bunch of different stories you can cut around. There was nowhere to cut to. It's these guys. We're not cutting back to anybody else.
Nothing would make me happier if Peter Falk would finally win his Oscar for this. Not just as the writer but as a fan and a friend. It would be so great.
