Re: Why Did Gene drop Christopher Pike?
My understanding is that Hunter's decision came from career advise he received from his wife, she wanted her husband to push for movies roles, and she didn't take seriously this little science fiction series out of a declining studio.
I heard a different but related rumor: Hunter's wife (or girlfriend, is what I heard) came into the studio behind Hunter's back and started making contract demands on his behalf. Some of those demands verged on the unreasonable; Hunter was dropped because the girlfriend would have made him unmanageable.
No butterflies were harmed in the filming of this episode.
