Photo: Vin Diesel Posing With Groot

It’s hard to believe but Marvel Studios still hasn’t confirmed that Vin Diesel will be be playing the motion-captured talking tree character Groot in next year’s “Guardians of the Galaxy”.

Diesel isn’t so hesitant though, posting on Facebook today the following image of himself with a human-sized bust of the character. The film’s director James Gunn also tweeted the image saying: “Vin Diesel is a super awesome dude. I can’t tell you how much I like this guy.”

Gunn went on to confirm that Diesel is in the role and has begun recording sessions for the film: “He was never announced. He said he wanted to do it and we said we were talking to him. Everything else was people guessing and thinking they knew what was going to happen. I hope this puts to rest all the silly Thanos-Vin stuff which people just seemed to make up out of nothing.”

Update: FINALLY, has officially confirmed the news.
