The actor, who played Brian O’Conner, died midway through production of Fast & Furious 7, and the film ended up being a celluloid tribute to the actor, who had become a star thanks to the successful action series. Paul died in November 2013, after a Porsche he was a passenger in crashed into a lamppost and burst into flames. His friend Roger Rodas, who was driving, also died.

Three films that he was involved in at the time were released posthumously; Hours, Brick Mansions and Furious 7.

Paul’s brothers, Caleb and Cody, stepped in to double for their actor brother to finish filming crucial scenes that allowed Furious 7 to be completed with Paul’s character still an integral part of the film.

Despite the seventh film in the franchise serving as a farewell to the star, Caleb revealed his family have given their blessing to the idea of featuring Paul in the next film in a cameo appearance.

“I had a phone call with Vin (Diesel) for about an hour and we really discussed this a while back. He wanted (our) blessing,” Caleb shared in an interview with Entertainment Tonight.

Vin had asked if it “would be acceptable to maybe bring Paul’s character back... to really kind of let his fans know he’s still out there.

“Universal wants to make sure to be respectful of Paul and his image too, and his family,” Caleb added.

A posthumous appearance is not unheard of in Hollywood. During the filming of Gladiator, British actor Oliver Reed died unexpectedly of a heart attack, so digital wizardry was used to provide two minutes of scenes following his death.

Caleb and Cody made their comments ahead of the second annual Game4Paul fundraiser which benefits the late star's disaster relief nonprofit organisation, Reach Out WorldWide, as the dedicated siblings continue to work to honour their brother's memory and legacy.

While their appearances in Furious 7 helped to finish the scenes started by Paul, it also "absolutely" helped the pair to grieve and come to terms with their painful loss, as they heard stories about their brother from Vin and his co-stars.

"We got to understand more about Paul, and what he was all about," explained Caleb. "We had to share Paul with a lot of people, in a weird way. He was gone a lot, he was filming, so we missed him. “Sometimes at the holidays he wasn't always there, you know? He tried. We'd see him on set, we visited a few times, but to kind of get that closure and understanding (of) Paul was really special."
