8. Vin Diesel vs. Dwayne “The Rock” Johnson

The tension between Vin Diesel and Dwayne Johnson, which started during the filming of The Fate of the Furious, made headlines when The Rock posted an Instagram message criticizing unnamed co-stars for unprofessional behavior. The feud escalated further when Dwayne was left out of Vin’s post-celebration after filming wrapped.
While both actors later downplayed the situation, their beef over the Fast & Furious franchise is a reminder that even Hollywood’s biggest stars can’t always get along behind the scenes.
