I read a Star Trek autobiography by the actress who played the part of Uhura. She mentioned that William Shatner came to her to get info for his own Star Trek book and remembered how chummy the actors used to be. The Uhura actress contradicted Shatner and told Shatner that everyone HATED him.
Wasn't it George -- what's his name -- ? He played Sulu, said that Shatner was kind of that crazy Uncle Bill everyone has in there family.
