I'll 2nd some of you guys.
Terrance Howard - I saw Red Tails. Terrible movie. They had a palette of good story opportunities and made it numbing and formulaic. And they had ILM magic.
I fell asleep and woke up to this movie, and few minutes later, Howard's character straightens someone out. The dialogue was bad towards the end, it follows a cookie cutter script where he softens out and lets his subordinate go without punishment.
But, golly, Howard kind of made that scene awesome for a few moments.
Michael Pena - I pretty much enjoy everything is he in. He does it well, and if it wasn't for looking distinctive, he would have a bit more of the Gary Oldman morphing techniques.
My own offerings:
Dwayne Johnson - he will be forever typecasted in the same role. That's okay. He does the charismatic bro thing so well.
Armie Hammer - I would like to see more movies with him, he seems to do a good job even in mediocre movies.
