Michelle Rodriguez Applies the Unix Philosophy to Acting
The short version of the Unix philosophy is basically, "Do one thing, and do it well".
Michelle Rodriguez basically plays the same basic character in every movie: tough girl / tomboy who doesn't take crap from anyone, usually wears a tank top, and dies about as often as Sean Bean.
And it's not a bad thing.
While I haven't seen every film she's done, I have seen a lot of them, and she gives a stellar performance every time.
So she may play the "same character" over and over, but she does it very well.
Yeah, it is. But I think MR is probably one of the most typecast actors out there. I read a while back that she is well aware of that and even supports it.
Edit: Not the article I was looking for, but has the same gist in a different interview:
She was in Halo 2! I forgot about that. I think she was already big but just wanted to do it. On the Resident Evil commentary she talked about how she loved Half Life and smashing zombies with a crowbar so she probably was a fan of Halo as well.
