Vin Diesel, who plays Dominic Toretto in the Fast and Furious franchise, has been accused of delaying production of the seventh installment of the film, which is currently underway in Los Angeles.
The actor is refusing to co-operate with the production, prompting a part of the crew members to wish they could use the CGI face replacement technology, which was being used to finish the late Paul Walker's scenes, according to The Hollywood Reporter.
"Vin spent a whole day in his trailer one day," said the insider. "The next day, they waited four hours for him. He called a meeting [May 28] of studio execs to his trailer for two-and-a-half hours to say, 'What the f- am I doing here?'"
However, Donna Langley, chairman of Universal pictures, dismissed the reports but did admit that they are working through some challenges.
"This production is working through some challenges that are historically unprecedented," she said. "The crew and cast, led by Vin, have been nothing but terrific under these circumstances."
"Fast & Furious 7" is in its last leg of filming, and a recent report stated that the production house is in search for 600 extras for the final shoot on 7 July in the Kern and Antelope Valley areas.
"Fast & Furious 7" is set for a 10 April 2015 release. Besides Diesel, the cast include Luke Evans, Tyrese Gibson, Ludacris and Jordana Brewster.
Brian O'Connor, the character played by Walker, will be shown as retiring in the seventh installment of the hit series.
Last month, photos emerged of Walker's younger brother Cody standing in for his sibling and helping the production house film some crucial scenes.
Leaked photos from the Malibu set of "Fast & Furious 7" showed Cody walking on the beach with Brewster, who plays the role of O'Conner's wife, Mia Toretto, and their on-screen son, Jack.
Filming of "Fast & Furious 7" was put on hold following the car-crash death of Walker, who had shot a majority of important scenes before he died. Although speculations were rife that Walker's character would also be shown as dead in the movie, the production house later decided to "retire" the character, in a way that would satisfy fans of the franchise.
