1. Sam Rockwell (Three Billboards Outside Ebbing, Missouri)
In a category filled with lovable character actors who have gone unrewarded by Oscar, Rockwell seems to have charmed his way to the top. After taking the Globe, SAG, and BAFTA, he's hoping to add an Oscar to his mantle.
2. Willem Dafoe (The Florida Project)
While Dafoe began the season as the clear frontrunner (at least among the regional critics groups who preferred his work in this category to all others), he may have to be content with just the nomination, which is his third in this category after Platoon and Shadow of the Vampire.
3. Woody Harrelson (Three Billboards outside Ebbing, Missouri)
This category thinned early on in the season in an odd way (that'll happen when Dafoe and Rockwell are hogging all the wins between themselves), but as Three Billboards continued to rise, so did Woody. He was last nominated for 2009's The Messenger.
4. Richard Jenkins (The Shape of Water)
Another respected character actor (sensing a pattern?), Jenkins was last nominated for Best Actor for 2008's The Visitor.
5. Christopher Plummer (All the Money in the World)
Third nomination (1 win).
Pretty stunning to think that this performance didn't even exist until late-November of last year and now it has earned Plummer his third nomination in this category.
