I've never been cool and I don't really care about being cool. It's just an awful lot of time and hair gel wasted.

'Sparkle' fell into my lap. I had heard a little bit about it that it was being redone in early 2011. I was just kind of like 'Oh that would be really cool ' and not really thinking too much about it and then it came through my agency. I read it I fell in love with the script and I went in to audition.

Being cool having a 'cool' energy is just not attractive to me.

I think I'm drawn to more villain-type characters because it's so cool to get to say all the things you want to say. In Hollywood you get to this position where you have to bite your tongue so much. You take all your experiences of not being able to say what you really want to say and channel that through your character.

I was trying to break out of the suburbs and when I did break out I don't think I took my whole self with me - I think I played a role of being too cool and hip.

And of course I've got kids of my own now and they love me being in the Harry Potter films. I'm now part of a phenomenon. You become incredibly cool to your kids and you get a young fan base. So you became the cool dad at school. You're suddenly hip.

When I entered high school I was an A-student but not for long. I wanted the fancy clothes. I wanted to hang out with the guys. I went from being an A-student to a B-student to a C-student but I didn't care. I was getting the high fives and the low fives and the pats on the back. I was cool.

It's interesting to feel the pressure of having to be outgoing because I think in general as a human being I'm pessimistic and introverted. But it's cool because it's a whole different side of me and I impress myself. Even at times when I think that there's no possible way that I can be engaging I'll suddenly pull it out and impress myself.

Playing well with others is important - not being too flashy just keeping good time and of course coming up with cool beats. A good snare drum kick drum high hat. Just getting good at the hand feet coordination.

I remember being on film sets when I was younger and only men got to do the cool action movies. So I thought 'Maybe I'll get to produce one day and get to do cool stuff too ' which is what happened when we did 'Charlie's Angels.' Starting my production company was a big turning point for me.
