Alright, we admit it: we really want Cillian Murphy in this movie. While the 'Inception' actor would be a fine fit for Plutarch, we can also picture him as District 3's male tribute Beetee. Sure, he's a little young for the role (hey, that's what aging makeup is for!) because if anyone looks like they might be a techie, it's him. Runners-up: Adam Scott, Jon Hamm, Mark Ruffalo, Edward Norton.
