Worf
De acordo com este artigo no TrekToday, Michael Dorn (tenente Worf) quase deixou o show após a segunda temporada, afirmando que sua maquiagem estava causando danos à sua pele:
Dorn said that he was very happy when his makeup time was reduced from
two and a half hours to a little over and (sic) hour, confessing that he
nearly left the show after the second season because of all the damage
to his skin. At one time he did a convention nearly every weekend, but
now he does 3–4 a year, "the really cool places" like Italy and
Germany. For fun he flies ex-military jets.
Sulu
Este relatório de entrevistas Comic-con afirma que George Takei (Sulu) quase deixou a série original depois que ele foi feito para compartilhar um camarim com Walter Koenig (Chekov):
When Takei returned, the two had to share a dressing room and a single
episode script. This reportedly angered Takei to the point where he
nearly left the show. But the two actors have since become good
friends, and the image of their two characters manning the helm of the
Enterprise became iconic.
Spock
De acordo com Jornada nas Estrelas: Estas são as Voyages TOS Season 2: Season Two , Leonard Nimoy quase não voltou para a segunda temporada de TOS devido a problemas contratuais. Há detalhes adicionais sobre Memória Alfa :
Nimoy's agent had asked for Nimoy's salary to be increased from
US$1,250 per episode during the first season to US$9,000 for the
second season. Eventually a compromise figure of US$2,500 per episode
was reached and Nimoy signed on for the second season.
Janeway
De acordo com uma entrevista com o Starlog , Kate Mulgrew disse que ela considerou recusar-se a assinar um sétimo temporada, citando sua impaciência por ter sido obrigada a esperar o dia todo por tiros em episódios focados em outros membros do elenco. Por fim, os produtores do programa conseguiram resolver as coisas com ela:
...she would be sitting at home for hours, unable to go anywhere or do
anything, waiting for production to call her in. And she didn't want
too many more instances in which she shot only a single, non-essential
scene.
Berman and company heard Mulgrew out, and ultimately they came to an
agreement that satisfied everyone. Janeway wouldn't be pulling a
vanishing act this year or next. Just how close, though, did we come
to losing Mulgrew? "If they had said to me, 'We really don't care,'
I may have considered leaving," she responds. "I was under contract
already for the sixth year and I intended to honor that contract.
I'm only talking about conversations and negotiations for the
seventh season. It really involved my happiness quotient. In
many ways, I set the tone on the set. My mood and my approach are
very important, and I think there's nothing worse than a professional
actress who is unhappy because she misses her husband and
children. But [Berman and Braga] realized that. And if I may say so,
they were not only gentlemen about it, but very gracious. I am much,
much happier now."
