Comingsoon.net chatted with Steven Spielburg and it said:
Spielberg then talked about what a great addition Shia LaBeouf has been and how he's been doing all of his own stunts, too. Speaking of LaBeouf, Spielberg told us there are going to be multiple "Transformers" films that the hot young actor is signed on to do and that there's already a story for the second one, but production depends on the pending writer's strike.
