In comic acting, to improvise effectively is quite difficult. A lot of actors can improvise up to a certain level - an entry level, which is when you see the actors having more fun than the audience.
I always find it easier to portray myself as being unlikeable and idiotic; to actually play a character that is likeable and engages the audience is far more difficult. It`s a more subtle kind of challenge.
I don`t want to be someone who`s trying to spin this public image of me. I have had some negative tabloid press, I`m sure you`re aware [I am], but I don`t like to portray myself as somehow a nice, well-rounded person.
