Body doubles, stunt doubles, and archive footage were used to complete the film following Paul Walker's death. Walker's brothers Caleb Walker and Cody Walker were among the doubles, and also provided voice-over for the character Brian O'Conner.
Production on the film was halted on December 1, 2013 following the tragic death of Paul Walker, who was killed in a car crash on November 30, 2013. Shooting had been underway in Atlanta and the film was scheduled to be released on July 11, 2014. Director James Wan and Universal executives held a conference call to determine how to proceed with the production in a manner respectful to Walker's memory. Walker was nearly halfway through filming at the time of his death. Although there was some consideration about scrapping the film altogether, the film eventually resumed productions following rewrites to address Walker's absence and give his character a proper send-off.
Some of Paul Walker's dialogue and footage was taken from previous Fast and Furious films. For example, Brian's conversation with Mia in the Dominican Republic garage is actually a deleted scene from Fast & Furious Five (2011). Similarly, the plane conversation between Dom and Brian has every shot of Walker rotoscoped from the conversation with Dom about their fathers from the same film.
Jordana Brewster (Mia) had to shoot her scenes at the very end of filming, because of her lead role on the since-canceled Dallas (2012) television series. She has stated that it was immensely difficult, given that most of her scenes were with her onscreen husband Brian, and by the time her scenes were filmed, Paul Walker had already died, requiring her to perform scenes with either one of Paul's two brothers acting as his body double, or with him inserted via computer graphics, or footage from an earlier film.
The guard rail that the heroes stand near overlooking Los Angeles is the same road/parking lot that Brian initially tests his Eclipse from the first movie.
