Mark Sinclair, known professionally as Vin Diesel, is an American actor and filmmaker. One of the world's highest-grossing actors, he is best known for playing Dominic Toretto in the Fast & Furious franchise. Diesel began his career in 1990 but struggled to gain roles until he wrote, directed, produced, and starred in the short film Multi-Facial (1995). This attracted the attention of Steven Spielberg, who was developing Saving Private Ryan (1998), and re-wrote elements of the film to allow Diesel to appear in a supporting role. Diesel subsequently voiced the titular character in The Iron Giant (1999) while gaining a reputation as an action star after headlining the Fast & Furious, XXX, and The Chronicles of Riddick film franchises. Diesel voices Groot in the Marvel Cinematic Universe, beginning with Guardians of the Galaxy (2014). He also voiced the character in Ralph Breaks the Internet (2018). Diesel has also earned commercial success in other genres, such as in the comedy The Pacifier (2005), while his performance in Find Me Guilty (2006) was praised. Diesel portrayed the comic book superhero Bloodshot in its 2020 film adaptation, and is slated to appear in the Avatar sequels. He founded the production company One Race Films, where he has also served as a producer or executive producer for his star vehicles. Diesel also founded the record label Racetrack Records and video game developer Tigon Studios, providing his voice and motion capture for all of Tigon's releases.
