“I have seen rumors that the cast hated Shatner during Star Trek”
They did but later Shatner said he was an idiot and became friends with all of them except George. I remember in the 70’s Shatner saying Trekkies were idiots and they needed to get a life and move out of their parents basement. He has since apologized for that comment and has become a regular at comic cons.
Sounds like life emulating “Galaxy Quest” or it was based on fact,
