'Fast And Furious 7' Will Move Forward, Says Director

There is still no confirmation on the cause behind last weekend's tragic car accident that claimed the life of actor Paul Walker.

Walker, 40, died in the passenger seat of a Porsche Carrera GT on a break from filming Fast And Furious 7. Police believe speed was a factor, however it's possible there was a mechanical failure. With production on Fast 7 postponed as the cast and crew mourn his death, some were uncertain whether or not the film would move forward at all. But according to the film's director James Wan, the show will go on.

TMZ stopped Wan at LAX airport in Los Angeles, and asked him a few questions on production of the film. He admitted the cast is very "sad and somber" at the moment, and when asked if production would continue repeatedly said "yes."

Wan could have been coming into town for this weekend's Paul Walker tribute. On Sunday (Dec. 7), a memorial rally and car cruise will be held in Valencia, Calif. It is believed thousands of car enthusiasts will show up. It begins on Hercules Street, near the crash site and law enforcement is taking things seriously when it comes to the traffic they believe it will bring. They will be citing for any reckless driving too.

Yesterday, Walker's pal and Fast 7 co-star Vin Diesel shared another heartfelt message with fans via his Facebook page.

"When I heard, I immediately flew back to California, and went directly from the plane to his mother's house," Diesel wrote. "I thought they needed my strength, but realized when I got there and broke down before his family, that it was I who needed theirs. His mother hugged me and said I am so sorry... I said sorry? You're the mother who lost a son?... She said yes, but you lost your other half..."
