Ever since he teased a meeting with Marvel Studios on his self-run Facebook page in June, The Fast & the Furious franchise star Vin Diesel has been the subject of much speculation regarding his future in their cinematic universe. Today, Diesel returned to Facebook and posted the below image. It looks like James Gunn’s Guardians of the Galaxy has found its Groot!

Admittedly, Diesel’s clues have been a little tricky in the past. He had posted a photo of himself standing in front of the second issue of “The Avengers,” leading many to assume he was up for a role in Joss Whedon’s Avengers: Age of Ultron. It’s a good bet that that was a clever red herring on Diesel’s part and he’s getting a kick off the Groot reveal. After all, Groot, the living tree creature, only speaks the one phrase, “I am Groot!” That would also serve as a nice wink to Diesel’s early voice role as the title character of The Iron Giant.

Assuming the casting is set (it is curious that this news wasn’t revealed at this weekend’s D23 Expo), Diesel will join Chris Pratt, Zoe Saldana, Dave Bautista, Lee Pace, Michael Rooker, Karen Gillan, Djimon Hounsou, Benicio del Toro, John C. Reilly and Glenn Close in the August 1, 2014 release.
