Diesel's no stranger to both Marvel teases and fan art. Before being announced as the voice of Groot, Diesel posted a classic pic of the anthropomorphic tree to social media. He was also relatively transparent about his initial meetings with Marvel and posted about them as they happened. Diesel's also posted fan art to his Facebook page that ties him to Kojak, angels and Santa Claus.

Marvel's "Inhumans" does not yet have a director, writer or any actors attached. "Marvel's Agents of S.H.I.E.L.D." is currently doing a lot of heavy lifting for the feature film by introducing the race and a lot of their essential concepts into the Marvel Cinematic Universe. "Inhumans" opens on November 2, 2018.
