To the cast of the Fast & Furious franchise, Paul Walker was more than a co-star, he was family. When Walker tragically lost his life over Thanksgiving weekend in 2013 while in production on Furious 7, the decision to continue with the franchise was difficult.

"It was a very emotional time," Vin Diesel told ET’s Brooke Anderson. "The idea that the brothers came in only strengthened our resolve and only strengthened our conviction to carry on."

Production on Walker's final film resumed after a four-month hiatus following his death. Fittingly, his brothers Cody and Caleb stepped in to film the rest of his scenes.

"I think everybody came out of the woodwork to make sure that the legacy is intact, because it's special and somebody very dear to us is gone," said Michelle Rodriguez.

"They are the true champion in this all," Tyrese Gibson said of the Walker Family. "When you see them laughing and smiling and giving good energy you're like, 'Okay, well maybe I should figure out a way to be okay.'"
