Walker's brothers join Fast & Furious 7

Paul Walker’s brothers have joined the cast of Fast & Furious 7.

Production on the racecar film was halted temporarily after the actor passed away at the age of 40 late last year in a fiery car accident.

But it appears Fast & Furious 7 is back on track, as Paul’s siblings Caleb and Cody stepped up to lend a hand.

“Caleb and Cody are helping us complete some remaining action for their brother and fill in small gaps left in production,” a message posted by Tuesday Universal on the movie franchise’s official Facebook page read.

The statement went on to discuss how much of a positive impact Paul’s relatives are making on morale.

“Our family experienced an unthinkable shock in November. We had to take time to grieve Paul, the brother we love and lost, and to figure out if we should move on with our film,” the post detailed.

“Having [Caleb and Cody] on set has made us all feel that Paul is with us, too.”

Paul portrayed protagonist Brian O’Conner in the speed racing movie series.

His co-star Jordana Brewster spoke about how much he is missed by Fast & Furious castmates earlier this month.

She developed a close bond with the late star while they worked together and is nervous about resuming work without Paul there.

"I'm looking forward to being back with the Fast family, but there's definitely a key element missing," Jordana told E! News, noting his colleagues will do everything in their power to keep the brightest memories of Paul alive.

"I'm sure it will be very bittersweet. We all just want to honour Paul going back,” she revealed.
