If you got a good imagination, a lot of confidence and you kind of know what you are saying, then you might be able to do it. I know a lot of colorful characters at home that would make great actors.
Some of my favorite movies are action movies. You want something good to say. That comes from good writing. But writing is not a skill I possess, unfortunately.
I know, a lot of the films I've done, it's obvious I'm going to beat up six guys and just walk out the door. There's not a lot of motivating factors - it's just action for the sake of action.
