Therin, I know you've been saying for awhile that the "standard contract" is five years and that may well be, but what was the story with Patrick Stewart's TNG contract, then?
Simple. He was the lead actor. Highly respected. Not used to being tied to a long contract. Yearning to return to stage work. His wife in the UK (at least for part of that time). His agent noticed that actors signing to new shows were already getting more money in their first year than Stewart would be making in his fourth. The third season had rated extremely well:
#1 syndicated, first-run, one-hour drama. Stewart's agent would have tried a little leverage for
some kind of better deal. When your lead actor is unhappy, you offer him reduced hours, a longer lunch, a better trailer, a private phone, a chance to direct an episode, a bigger cut on merchandise, etc. Crosby had already asked for an early release. They wouldn't have wanted Stewart to contemplate doing so, although Paramount ended up doing very well with the
rumours that he was renegotiating.
I even vaguely remember reading a (Roddenberry?) quote along the lines of "Well, it was all deliberately planned, we were going to rest Bev for a year, then bring her back."
Well
someone said that, but it wasn't how it had panned out. Roddenberry's famous comment to the "Bring Back Bev" Brigade at a big convention was, IIRC,
"If I listened to the fans on how to make television, 'Star Trek' would be shit."
My personal supposition is that the rumours about contractual difficulties with Stewart leading to further rumours about him not returning in season 4 etc were not just untrue but were in fact deliberately created by Paramount...
But look to ENT for the same problem. Even though Scott Bakula had an iron-clad, standard, five-year contract, he complained bitterly (two years running) about the long hours away from his family, and that few other shows were doing 26 episodes per season any more - and the producers bowed to his wishes
and reduced the number of episodes in Season Three (by two) and Season Four (by four) partly to appease him.
