I always wanted kids but I always thought I'd have kids later on in my life, maybe when I turn 30. I really wanted to focus on my career, but you meet the right person and your whole world changes.
It is always more fun to play a bad guy than to be yourself as you can create a character unlike your own and be someone you are not for a change.
For me and for I'm sure any actor, each role is a different challenge to prepare for in a different way.
