While attending the Texas Frightmare Weekend at the beginning of May, Transformers' Glenn Morshower told fans that he would not be in Transformers 4 citing a scheduling conflict as they had begun filming and he couldn't fit the film in. Last year the actor had said he though he would be in Transformers 4 and 5 so I guess the story changed and didn't need his role of General Morshower. Considering Michael Bay frequently has said Transformers 4 is going in a different direction, losing the military angle would be a good start. Thanks to Shane E. for the info.
