Michael Fassbender (X-Men: First Class)
Heading into 2011, Michael Fassbender was a relatively unknown actor's actor. In February, David Cronenberg told EW, ''Although he's not that well known to the public yet, everybody thinks Michael's quivering on the brink of major stardom.'' Now, heading into 2012, the quivering has stopped and Fassbender has arrived, thanks to four unshakable performances. In March, he gave Jane Eyre's Mr. Rochester a moody, broody makeover. In June, he struck box-office pay dirt as the young Magneto in X-Men: First Class. Now, with awards season in full swing, Fassbender, 34, has folks buzzing again with his turns as a kinky Carl Jung in Cronenberg's A Dangerous Method and an even kinkier Manhattan sex addict in Shame. ''I haven't had time to stop and think,'' says the actor of his busy year. ''Maybe I should be worried that after all these movies, people are going to be Fassbendered out.'' Somehow we doubt it.
