When it comes to Marvel movies, Vin Diesel isn't shy about sharing his opinions. The actor, who voices Groot in the "Guardians of the Galaxy" films, has talked about everything from wanting to see an "Inhumans" feature film to hoping that Groot and the Hulk clash in "Avengers: Infinity War." Now Diesel has another suggestion for the minds behind Marvel Studios: give Groot a solo movie.

While speaking with MTV International, Diesel said that he sees a potential Groot spinoff film as "inevitable."

"It's something that James Gunn has talked about and it's something that I know he would love to do," said Diesel. "Sure, I think it could be very interesting. I think it's inevitable. I think -- you know, that character is so enigmatic and he was already one of the most unique characters in the Marvel universe. And I think what Marvel has done, primarily what James Gunn has done, has started to realize that character and he's exceeded beyond expectations. I think he's just such an interesting character and there's so much to learn about him. And I'd love to go back to his planet and learn more about him and I think the world would. He's really a genius on a lot of levels, it's just that we can only hear him say 'I am Groot' because of our sophistication level, not his."

This isn't the first time Diesel has talked about a potential "GOTG" spinoff film. Back in December, Diesel spoke about "Guardians of the Galaxy" director James Gunn's interest in doing a Rocket Raccoon and Groot team-up film. During an interview back in December, Diesel said, “I think if it’s up to [“Guardians of the Galaxy” director] James Gunn, you are going to see a Groot and Rocket movie after ‘Infinity War.’ I think that’s highly possible. We shall see.”

This is the latest Marvel idea shared by Diesel. Last week he weighed in on the shelved "Inhumans" film, saying, “I think Marvel should never — I don’t think Marvel should abandon their opportunity to make a film out of it. I think it could be a huge, huge saga, and if I had more time I would go over to Marvel and have that very conversation. But I think it would be a big mistake for Marvel to abandon their ambitions or their objective or their goals of making it into a film, because it would make such a cool universe.”

Opening May 5, “Guardians of the Galaxy Vol. 2” also stars Chris Pratt, Zoe Saldana, Dave Bautista, Bradley Cooper, Michael Rooker, Karen Gillan, Sean Gunn, Glenn Close, Elizabeth Debicki and Chris Sullivan.
