Vin Diesel already provided the voice of Groot in Guardians of the Galaxy, but now the actor is hinting that he might play a second role in the Marvel cinematic universe.
In a conversation with io9 to promote The Last Witch Hunter, Diesel said he might play a totally different, silent character in an upcoming Marvel movie.
"We’ve heard a lot of talk about Marvel wanting to have me play a character that doesn’t have my voice," he said. "So my voice is used for Groot and my presence is used for the other character."
Marvel fans are already going wild speculating what character he could play that wouldn't require a speaking role. The most common theory is that he could play Black Bolt in Inhumans. That character has the power to unleash massive destruction using only his voice, but since it's so dangerous, he usually keeps quiet. In fact, Diesel has hinted at a possible Inhumans role before, as when he posted a Facebook status saying, "I get the strange feeling that Marvel thinks I'm Inhuman."
That would work out pretty well if true, with one role that requires Diesel to only use his voice and one that requires him to only use his physical presence. The actor has also discussed how much he enjoyed working with Marvel on Guardians, even though it was only in a recording booth, so it would be great to see him actually get to have some fun on screen in Inhumans.
