Actors who are the same in every movie.

In my opinion there are actors who never (or rarely) change their acting style regardless of the movie. This isn't about type-casting but more...bad acting? I'll offer some and I'm curious to see what you think.

George Clooney. Overrated in my opinion and I challenge you to point out any difference between Danny Ocean, his version of Batman (with the regrettable nipples armor), and Seth Gecko.

Jesse Eisenberg. Can't stand his constant "nerdy guy" with lots of tedious monologing delivered in his trademark staccato.

Samuel L. Jackson. Angry Black man. Enough said. No? Say what again.

Edit: because some of you have correctly pointed out that each of my examples have good movies...you're not getting the assignment. This isn't a debate on if they have ever made a good movie, but an attempt at a humorous list of actors who most of the time act the same.
