Speaking of "Assignment: Earth" I happened upon Teri Garr's memoir in the public library recently, and there are a few pages devoted to her appearance in the episode, which I cited to create the following addition to her WIkipedia article (LINK): The same year she landed her first significant TV role, featured as secretary Roberta Lincoln in the Star Trek episode "Assignment: Earth", designed as a backdoor pilot episode for a new series which was not commissioned. "Star Trek was the first job where I had a fairly big (for me) speaking part," Garr related in her memoir, "I played Roberta Lincoln, a dippy secretary in a pink and orange costume with a very short skirt. Had the spin-off succeeded, I would have continued on as an earthling agent, working to preserve humanity. In a very short skirt." This led to her being, in her words, "cast as birdbrained lasses," in episodes of other TV shows. She doesn't say anything bad about the experience, but from what she's said over the years it seems apparent she's glad the show wasn't picked up, possibly because she had a pretty great career after with a lot of good film roles and was not typecast the way a lot of actors in sci-fi shows have been.
