Vin Diesel has spoken up about filming “Fast & Furious 7” without his co-star Paul Walker. The 46-year-old also appeared to address recent reports that he was a jerk on set.

In November, Walker, who played Brian O’Conner in the multi-billion film franchise, met a fatal accident at the age of 40 in California. He was able to shoot most of his scenes in the latest film instalment, but there were still a few that need to be shot.

His brothers, Caleb and Cody, have stepped in to help the crew complete the film by sharing his role.

Diesel has informed his fans how Walker’s absence is affecting the production of the upcoming movie.

“There wasn’t a scene in the saga he didn’t want to discuss, improve... even with just a changing of a line or adding a specific nuance to enrich a moment,” Diesel wrote on his Facebook.

“He did it with the pride of knowing, that over a decade of portraying Brian, through four directors, multiple writers and new producers he was able to maintain the inner core of the character he created. Those work ethics and drive to be both truthful, and in his own way, evolve the decade spanning character is what made his character as iconic as it has become.

“He always knew I would fight for him... whether it was to protect his deal or to protect his integrity... and he knew that if it made for a better film, I was going to do whatever it took... it is why together, we won best duo... twice, 12 years apart.

“With our new ambitious vfx team, the whole cast and crew has had to adjust to this awkward and uncomfortable process of pixels over people. Aside from the obvious strains it places on the director, the challenge is not to allow it to compromise what makes the character so special.

“Happy Toretto Tuesday...”

Diesel’s message not only explained how they are faring without the late star, but also appears to have addressed the recent report that he was being difficult on set.

According to The Hollywood Reporter, Diesel “has been so difficult that some on set have fantasised about using the facial-replacement technology being deployed to put Walker in the film as a sub for Diesel as well.”

Universal Pictures chairman Donna Langley has denied the claim, saying that Diesel and the cast and crew have been “terrific” despite the fact that they are working under some challenges.

“Fast & Furious 7” is scheduled for release on April 10, 2015.
