Most famous role: Colonel Wilma Deering in Buck Rogers in the 25th Century (1979-1981)

Television's first female colonel—she was the right-hand woman to Buck Rogers—knew how to wield a weapon and rock a tight white jumpsuit. It was so tight, in fact, that Erin Gray claims she needed to be sewn into it on the set. Gray's discomfort didn't seem to bother audiences.
