Vin Diesel may have revealed that he's going to be the voice of Groot in Guardians of the Galaxy. Not long ago Diesel took a meeting with Marvel but didn't say what it was for. We've heard rumors of him playing Vision, which Joss Whedon debunked, and I've speculated that he will play Thanos, which I'm still really hoping for! But yesterday the actor posted this picture on his Facebook page. There was no explanation for the image, and the dialogue was whited out, but the character's signature line is "I am Groot!" In fact, I think that's the only thing he says!
He could have also just posted it as a way to tease that he'll have a role in Guardians of the Galaxy, maybe as Thanos? Maybe he posted it to throw everyone off the scent of who he's really going to play in the Marvel universe.
Only Marvel and Diesel know the truth, but if he did end up being the voice of Groot, that would be cool! After all, he also famously voiced the robot in Iron Giant. I won't complain, but I still think he'd make a better Thanos.
What do you think Diesel is trying to hint at?
