Oh thank goodness, LaBeouf can't pull off Yorick. He can pull off being hammy and bland but definitely not a character so likable. Some peopl are saying Yelchin and i honestly haven't seen much of his work but in Star Trek he was pretty awful with the impersonation especially in contrast to the rest of the cast's stellar performances.

Ryan Reynolds could be good and he might not be too old. I mean, Yorick could be played anything from mid-late 20's right? He is charismatic but maybe too mouthy.
Oh, please no one say emille hirsch.
