According to Variety, Vin Diesel's One Race Films production shingle is partnering with Blur Studio to make a CGI feature based on the indie toon house's short Rockfish.
The thesp will voice a lead character in the sci-fi actioner, which will likely be aimed at a more mature audience than most studio-produced digitally animated pics.
One Race is now seeking independent financing for the production, which it hopes to bring in for under $30 million.
Diesel will produce with One Race partner George Zakk and Blur creative director Tim Miller, who wrote and directed the short and will helm the feature.
Rockfish short is about a man on an alien planet trying to catch a giant "rock fish" that lives underground and disrupts the planet's miners.
Diesel provided the voice of the giant in WB's critically acclaimed The Iron Giant.
