What actor played a former FBI agent-turned-criminal in "Fast & Furious 6"?

In "Fast & Furious 6," Paul Walker played former FBI agent-turned-criminal Brian O'Conner.

Brian began the franchise as an undercover LAPD officer investigating Dominic Toretto's street-racing crew in 2001's "The Fast and the Furious." His decision to help Dom escape made him a fugitive, and he later became involved with Mia Toretto and Dom's criminal team.

By "Fast & Furious" (2009), Brian had become an FBI agent, but he eventually resigned after helping Dom. In "Fast Five" and "Fast & Furious 6," he is living outside the law while working with Dom's crew. The wording can cause a common mix-up: Brian was originally an undercover police officer before becoming an FBI agent, whereas Luke Hobbs, played by Dwayne Johnson, is the federal agent who recruits the team in the sixth film.

Released in 2013, "Fast & Furious 6" follows Dom's crew as they help DSS agent Hobbs stop Owen Shaw. Walker returned as Brian, one of the series' central characters, alongside Vin Diesel, Michelle Rodriguez, Jordana Brewster, and Tyrese Gibson.
