Vin Diesel is so excited for everyone to see him as Groot in the upcoming “Guardians of the Galaxy” flick that he just can't seem to get out of character. On Thursday, the actor sported stilts to the London premiere for the film and even donned a T-shirt that read, "I am Groot." In the flick, Vin plays Groot, an extraterrestrial tree-like creature. And for the role, he had to wear mechanical stilts in order to be taller. But he kept them on even after the film wrapped shooting.
