Alan Tudyk (Firefly, Dollhouse) has joined the cast of Transformers 3 according to thewrap. While the studio is keeping the story and his character under wraps, I’m hoping Michael Bay is going to use him in a fun role and not something dark and serious. Because if you’ve seen his work on Firefly, you know that’s the type of role he’s great in. He has appeared on the bigscreen in "3:10 to Yuma," "Knocked Up" and "Dodgeball," and most recently toplined "Tucker & Dale vs. Evil," which won the Audience Award at this year's SXSW Film Festival. Tudyk will next star opposite Michael Sheen and Maria Bello in Shawn Ku's school shooting drama "Beautiful Boy." Director Michael Bay plans to shoot "Transformers 3" at a variety of international locations including Africa, Moscow, China and of course, the U.S. The last two films in the blockbuster franchise have grossed over $1.5 billion worldwide. "Transformers 3" hits theaters July 1, 2011. Tudyk is repped by The Gersh Agency and Thruline Entertainment.
