Dwayne Johnson and Vin Diesel
While the actual reasons behind their feud are not clear, Dwayne Johnson has publicly clarified that the actors who seemingly are very similar do not work together anymore. In an interview with The Rolling Stone, he clarified that this is due to “different approaches to filmmaking”.
I wouldn't work with either of them. I don't much like being punched. ...or shot.
Snipes spent almost the whole time in his trailer getting stoned, barely showing up when needed, and at one point attacked the director trying to kill him.
Snipes basically left the production, half of his scenes unshot, leaving the rest to try to cobble together a movie with half rewrites and workaround scenes to make it a somewhat coherent movie.
It was the whole reason why the movie was so bad.
He refused to memorize his lines, and often couldn't even say them because of how baked he was. There's even a scene where, just to be a d@#k, he refused to open his eyes. They had to CGI the eyes in after.
