Improv is not something I had a lot of experience with, because for a long time, my only experience in front of a camera was all television, which is pretty rigid script-wise, except for the occasional scene where you toss in an ad-lib just to elongate something.

Then, at some point, you get identified with certain things.

I think it had something to do with my love of music, especially rock music.

I love going to concerts, so that whole environment is something that intrigues me anyway.

I will confess I did none of my own singing. I did all my own costume and makeup, though.

I like the fact that this kind of family has been seen in a movie a million times: teenage kids, the family is a bit strained and they don't have enough money, but in the background the guy used to be a Gene Simmons type.

You make the choice. You look at each scene and you make sure that this is not a person deceiving people.
