From original Battlestar Gallactica (Pictured in Man From Atlantis) star Laurette Spang's page on working with a monkey in a robot dog suit:
Then there was Muffit, Galactica’s K9 counterpart to R2-D2. “Oh I loved the daggit,” Spang notes. “What made the daggit so lovable was that there was a monkey inside. Evie the monkey always let you knows how she felt. There was one day on the bridge ¬– with the whole cast – and the daggit came running in, with that funny little sound it made.
“We’re all very tired, it’s the end of a long, long day on this huge set. Here comes Evie, who decides to pull off the daggit head and throw it on the floor! The director yells: ‘Cut, cut, cut!’ We stop, the trainer makes sure Evie was okay, they screw the daggit head back on, start up again – and Evie does it several more times. This monkey had just had it! She was letting us know: ‘No more. I am done.’ I worked several times with the daggit and always felt it should have played a bigger part in the show.”
