William Shatner gets jealous
According to reports, William Shatner isn’t the most cooperative actor in Hollywood. In fact, other Star Trek cast members reportedly despised their time spent on set with him.
He certainly acquired a negative reputation after feuding with castmates, as well as threatening to leave because of his behavior. He was also said to be irritated by the fact that his co-stars received more attention than he did and that their characters were smarter than his. Some of the conflicts have since been resolved.
