I'm old enough to remember the advent of CD. You thought, "What's this piece of space age technology that's in front of me?" Now I ask, "When's the last time you bought a CD?" You see things come and you see things go, and you have to be on your toes and be nimble and stay with it, or you die. It's exciting. I love technology.

Some films go so well, and some films are disappointing. It's the beauty of the craft. You get it right, and you get it wrong. You have tremendous highs, and you have tremendous lows. Hopefully, you learn from them and become better, as you go along.

If you look at what Ben Affleck has gone on to do, as an actor and as a director, it's extraordinary. But if you look back at his career, I don't think it's surprising. From Good Will Hunting on down, the guy is a monster talent, and I think talent wins out, in the end. There's always the ebb and flow of any career, but I think talent wins out, in the end.

It's really fun to create something that touches the world.

For me, casting is critical. It's nice that social media and the passionate fans really corroborated choices and embraced kids to be characters.

I felt a particular attachment, naturally, to the Superman character and really dug deep, but at the same time, I am a passionate fan, be it Star Wars, be it the entire Marvel catalog, be it the DC catalog, or the original thinking at Pixar. I'm a fan first, so I'm always curious to see the way people express themselves and how it's being done.

Actors can become very involved in a role, but for a director or producer, that's your life for many years.
