Busy or not. Its not impossible to make it happen. Patrick Dempsey was filming Grey's Anatomy and Transformers back to back and Patrick Dempsey appeared in all of the episodes of grey's Anatomy and was in Transformers 3 until near of the end of the movie. Plus they are filming this movie until October 2013. Thats quite a long time.
