Tyler Perry is a man of many faces ... and now the guy known for playing Madea is trying on a new one: Action star.

The actor plays the title role in "Alex Cross," taking over Morgan Freeman's role in the latest film adaptation of James Patterson's books.

In the just-released trailer, Cross faces off against a sadistic killer played by Matthew Fox -- who seriously bulked up for the role.

Sporting a shaved head and tattoos, Fox transformed his whole persona for the movie. But what do you think about Perry?

Are you ready to take him seriously in an action-heavy movie?

Sound off below. The movie opens later this year.
