“Friday’s Child” sees Captain Kirk (William Shatner) traveling to the planet Capella IV to negotiate a mining contract with the violent, but honorable, locals. Kirk has to convince the Capellans to give their ore to the Federation and not to a visiting Klingon (Tige Andrews) who would use it for nefarious purposes. During the negotiations, a civil war breaks out, with Maab (Dante) killing the Capellan leader and usurping the throne. Maab also wants to kill the pregnant queen Eleen (Julie Newmar), forcing Dr. McCoy (DeForest Kelley) to protect her. The episode features a lot of outdoor fighting, silly regal costumes, and over-the-top acting. Eleen eventually names her child after Kirk and McCoy.
Dante had to wear an outsize blonde wig to play Maab, as well as an uncomfortable-looking headpiece that covered his neck and ears (see above). The regal costumes looked to be made of disused theatre curtains and wool. As itchy as they appear, however, Dante said they were also filled with sweat:
“The weather [stands out]. It was 117 degrees at Vasquez Rocks, where we were filming. The outfits we had, they couldn’t breathe. There weren’t any openings in the clothing. They were all tight, with boots. I was 180 pounds at that time — and I’m still 180 pounds, which I’m very proud of — but I lost seven pounds in one day. I literally lost muscle. I looked at myself in the mirror when I got home and I said, ‘I can’t believe what happened.'”
Sweating too much doesn’t actually reduce muscle mass, but one can indeed lose several pounds of water a day if they don’t rehydrate in a hot climate. Keep the canteen full, kids.
