Vin Diesel isn’t shy about using his social media presence to trumpet exciting new projects to his fans. Now, the “Fast and Furious” star is using his Facebook page to tease a greater involvement in the Marvel cinematic universe.

As many know, Diesel has already carved himself a role in the comic book giant’s connected film and TV world. He provided the low yet friendly voice of Groot in Marvel’s 2014 hit flick, “Guardians of the Galaxy.” And on Sunday the actor posted a new cover photo showing him in what looks like an official “Inhumans” tank top and the words “Are you Inhuman?” behind him.  The studio recently announced that it will release a film in 2018 based on the “Inhumans” comic book, which was introduced in 1965.

It’s worth mentioning that the cover photo might just be fan art that the 47-year-old actor wanted to share. Diesel has since removed it as his cover photo but he didn’t delete it from the site. He’s had a pretty decent track record of putting real announcements on his social media in the past. He was among the first to report his casting as Groot, and his “Fast and Furious” updates have mostly been timely and accurate. As The Hollywood Reporter notes, Diesel may have hinted at his involvement in “Inhumans” back in August.

Diesel posted a photo of Groot on Facebook with the caption “Vin and Marvel… you all made it happen! I get the strange feeling that Marvel thinks I’m inhuman… Haha.”

The note seemed relatively innocuous at the time, as the studio had not yet revealed its plans for the “Inhumans” movie. Since then, the super-aliens have become a major plot point on “Marvel’s Agents of S.H.I.E.L.D.

Marvel doesn’t typically like to double down on actors in its vast expanded universe. However, since Diesel only delivers the voice of the CGI tree monster, it wouldn’t necessarily be the biggest suspension of disbelief to see him on screen in a different role. As points out, many fans of the source material believe he fits the look of the character Black Bolt, who coincidentally doesn’t speak. Could Marvel get Diesel’s voice in “Guardians of the Galaxy 2” and his face and body in “Inhumans”? Only time will tell.

Joining “Inhumans” would be a good move for Vin Diesel as the role would begin as the rest of the Marvel cinematic universe winds down. Marvel revealed plans for movies stretching through 2019. “Inhumans” is slated for the back end of those plans and has, arguably, the most franchise potential once “The Avengers” finishes its “Infinity War” plot line.
