The whole world mourned for Paul Walker when he was fatally killed in a car accident. The filming of "Fast and Furious 7" was halted as the filmmakers had to adjust due to Walker's absence. Now, filming has begun and it seems like the team behind "Fast and Furious 7" knows what to do.

They called in Caleb and Cody Walker, the look-alike brothers of Paul, to continue his role in the film. Caleb, the younger brother, will be Paul's double in some scenes. Cody, on the other hand, is said to join the cast of the movie franchise in the next movies too, according to Daily Mail. Both brothers agreed to be part of the movie as a tribute to their beloved brother.

A source for Daily Mail shared that "Paul's character Brian O'Conner will be seen retiring, while his younger brother will join the crew." The source also added, "Of course, Cody isn't a replacement for Paul in any way, but the producers were really grateful that he stepped in to help them finish this last film and Cody so likeable and charming. It would be a tribute to Paul that Cody carries on the Walker name in the 'Fast and The Furious' movies."

In an interview with AP earlier this year, Cody spoke about his late brother Paul for the first time. "It still doesn't feel real because sometimes, working in this industry, making films, he'd be away from his family three, four, six months at at time. My only interaction would be a phone call. I know it's going to take a while, it's going to take a few years before it feels real."

Cody, in tears, further added "Anyone that ever met Paul, he'd never met a stranger in his life. If you didn't recognize him out in public, he'd never mention it, he was so low key, just lived a modest life. He'd tell me how jealous of me he was, because I still had my anonymity. He'd say 'I can't just go to the movies and catch the film I want to see, you still got that man', it was so funny to hear that."

Paul will surely be missed as "Fast and Furious" fan will always have a memory of Paul and Brian O'Conner through his brothers.

Filming and production has resumed for the film franchise and "Fast and Furious 7" will hit theaters on April 10, 2015.
