Vin Diesel will star in STX's action comedy Muscle.

Diesel and One Race Films' Samantha Vincent will also produce the film, along with Reginald Hudlin and Byron Phillips, who brought the project to STX.

"I’ve known Vin for more than a decade after working closely with him on the Fast and Furious franchise, and I’m excited for him to return to this genre,"  STX film chairman Adam Fogelson said Wednesday in a statement.

Diesel also voices Groot in both of the Guardians of the Galaxy films and currently can be seen in Marvel’s Avengers: Infinity War. His upcoming projects include Sony's Bloodshot and then xXx4 — in which he will star and produce — which is slated to begin production in December.

Diesel and his One Race Films earlier teamed with finance and production company The H Collective to acquire the rights to the xXx action-adventure franchise from Revolution Studios.

Diesel is repped by CAA and Brillstein Entertainment Partners.

STX’s recent releases include I Feel Pretty, starring Amy Schumer, and A Bad Moms Christmas, starring Mila Kunis, Kristen Bell and Kathryn Hahn.
