Weta Digital, the company that brought Walker to life on the big screen thanks to visual effects, has revealed the extensive work.

It has also been revealed which scenes that Walker appeared in were created digitally.

Weta, which ended up doing 350 shots almost all of them with Walker, referenced old footage from outtakes of Furious 7 as well as the rest of the franchise to nail Walker’s expressions, not having the luxury of having a digital scan of Walker to use.

According to Variety, the team had to seek out Walker’s brothers, Cody and Caleb, in addition to Walker’s double John Brotherton, scanning them and “reapplying them to the Walker digital models they had created.”

Weta visual effects supervisor Martin Hill said

“We knew we were doing something special for the filmmakers, the fans, the family — and for Paul’s legacy. We wanted to give him the sendoff that he deserved.”
