It’s been months since Vin Diesel first hinted at voicing Groot in Marvel’s GUARDIANS OF THE GALAXY, but now he can officially shout, “I AM GROOT,” to his heart’s content. Marvel, Diesel, and director James Gunn confirmed the casting yesterday and released an image of the actor with a bust of his character that was used during principal photography. Gunn voiced his own excitement over the latest addition to an outstanding cast on Facebook.

Yep it is completely official. AND he’s amazing. I never knew someone could say I AM GROOT so many different ways and with such feeling (and that sounds like I’m kidding but I’m not!)

Diesel has done voice work before in IRON GIANT and brings a lot of star power to an unknown property that could certainly use the extra attention. Marvel is probably saving a pretty penny or two by hiring Diesel for a couple days’ worth of recording as opposed to paying his full quote for a live-action role. That’s good value for a studio known for its cost control while also preserving Marvel the option to cast Diesel in a live-action role in a later film, if it so chooses.
