Tobey Maguire has a range of 3 distinct faces that he applies to a wide variety of emotions incorrectly. A
pathetic sagged downward look that he uses for sadness [correctly], contemplation, and slight anger/coolness. A
wide-eyed look that he uses for absolutely everything from fear, anger, happiness, sexuality, and determination. And his
smile which he sometimes uses for anger and confusion, too.
I tried to find a picture but none of them are what I'm talking about. The only one that is clearly represented is his rote smile face. I would feel bad if I found out he had some kind of a nerve problem in his face, but I swear to god his eyebrows move like they're CGI.
Edit: found some good examples that reveal just how accurate my assessment is if you look at the google images page. There might be a 4th "flat face," but that's his natural whiteboard state it seems.
