William Shatner – bad personality on set
After playing Captain James T. Kirk in Star Trek, William Shatner became well-known overnight. He had hoped to reach stardom a bit later. However, he is less recognized for his unpleasant personality while filming these films than he is for other things.
While the camera was not rolling, he frequently made a nuisance of himself. He also disliked it when the director told him what to do, and he often used profanities. This made the whole filming to have a tense environment, all because of Shatner.
