Two giants in a feud? Now that’s some ‘beef’ of epic proportions. These co-stars didn’t get along at all due to having different fundamental philosophies regarding acting. The Rock had some problems regarding Vin Diesel’s behaviour on set, which he indirectly mentioned in his Instagram post as ‘candy asses’. Vin Diesel was reportedly always late to the set and had an unprofessional attitude. In 2016, there was an alleged ‘secret meeting’ between the two that resulted in a positive resolution.
