The tough guy act is no more real than anything else in his movies.
Shia LaBeouf has managed to land enough roles in enough big budget action films that he can now be considered an action star. And since these included the car-heavy Transformers movies, he's on our radar. But apparently nobody has told LaGoof that being an action star doesn't automatically make him Russell Crowe, as evidenced by this video where we see him trying to stare down a motorcyclist who doesn't seem to be in the least bit intimidated.
We seriously hope LaBuff was practicing for a role and trying it out on the motorcyclist. Although it's possible that the lane splitting was the issue. If so. we would like to remind our readers that it is completely legal in the state of California.
