Comedian T.J. Miller has joined the cast of Transformers 4, playing the best friend of Mark Wahlberg's character. The role, like Wahlberg, is a mechanic (one assumes race cars) but no name has been provided. If the actor seems somewhat familiar, he is currently one of the leads on Fox's The Goodwin Games that is airing on Mondays. He also was in Cloverfield and voices Tuffnut in the How To Train Your Dragon franchise.
