The newest cast member for Tron: Ares, the third film in the venerable Disney franchise, is the actor from Yellowjackets.
Desjardins joins a cast that also features Jodie Turner-Smith, Greta Lee, Evan Peters, and Jared Leto.
Ares, the third film in the Tron franchise after Tron and Tron: Legacy, is being directed by Maleficent: Mistress of Evil director Joachim Ronning.
The first Tron film starred Jeff Bridges as a computer game designer who entered his own creation, and the sequel followed him as his son (Garrett Hedlund) followed in his father's footsteps.
However, insiders previously told The Hollywood Reporter that the third Tron movie will spend more time in the real world.
According to the Jesse Wigutow and Jack Thorne script, the story revolves around a sentient computer program that enters the human world but is not yet ready for contact.
