I would visit Vegas every year when I was a kid. Vegas, to a kid, is a playground, as much as it is to adults. I discovered the magic store in a hotel and would spend hours and hours in there.

I enjoy both acting and screenwriting, in completely different ways. You have more creative freedom with writing because you can create everything that happens. But, as an actor you also have creative freedom because you don't so much focus on what has to move the story along, and only on how your character is reacting to situations.

As an actor going into screenwriting, I was able to understand what type of dialogue feels natural. A lot of the time, as an actor, you don't have the freedom to change what your lines are, and they can often be very unnatural or difficult to portray in a real light.

You become sort of insulated in this bubble when you're working on something that it's hard to have an outsider's perspective on what works and what doesn't so it's always good to see what other people think.

We always for better or worse try to put on paper what's going up on screen - whether we're directing it or not. It's really just an extension of that habit which is trying to tell the reader what the movie will look like. Ultimately that is the job of a screenwriter to a certain extent.

It's like live action if you reshot every scene a million times after finishing the movie. Because even apparently by the very end, a few weeks before they were screening it for the world premiere, they were making changes. That's just simply something you can't do on live action.

I think that's pretty crucial for it to succeed and be something more than just something you put your kid in front of and turn on the DVD. We wouldn't have got involved if it were just for little kids. We wanted to write something that works on both levels.
