The crew has chosen sides in the "Fast 8" feud between
The Rock" and
Vin Diesel" ... and Rock wins, hands down.
Production sources tell TMZ, The Rock has been upset with Vin's work ethic for a long time, and he's not alone. Members of the crew tell us Vin was often 30 minutes to an hour late to shoot scenes ... and it wasn't because he was late to the set -- he was simply in his trailer and wouldn't come out.
We're told Vin didn't like Monday 7 AM calls so production was forced to make the start time 10 AM to accommodate him.
And the crew felt Vin's arrogance was out of control, especially because he had a producer title. We're told he wouldn't listen to anyone and would goad people, including The Rock, by criticizing their acting.
The crew has a vastly different view of The Rock. They say he's the ultimate professional who is always on time and always nails his scenes. They also say he's easy to work with.
As we reported, Vin and Rock have been clashing for a long time and it came to a head Monday when Rock
exploded on social media, calling out a male co-star (it's Vin) for being unprofessional.
And as we told you, Vin confronted Rock Tuesday
in Rock's trailer, but their issues remain unresolved.
