I improvise whenever I feel it's important, or whenever I think that something's there. It's nice to have a script that's so well-written that I don't have to improvise. I mean, I used to have to re-write whole movies; this is kind of nice.
The studios don't seem to foster good writing. They're not so interested in that, but they're more interested in what worked most recently. They're definitely very serious about making money, and that's not a wrong thing, but you don't have to make money the same way all the time.
If you have a good script, that's what gets you involved. It's harder to write a good screenplay than to find something.
