Introduced in the two-part episode, "The Living Legend," Lockhart's Sheba was the daughter of the legendary Colonial Commander Cain, of the Battlestar Pegasus. A tough and tough-minded Viper pilot, Sheba was the equal of Captain Apollo or Lieutenant Starbuck. At the end of that classic two-parter, she remained on the Galactica as both a new love interest for Apollo and number three Viper pilot, pretty much supplanting the character of Boomer in most adventures. Sheba was strongly independent, but definitely feminine, and was a great addition to the crew.
Pretty, perpetually pouty Anne Lockhart is the daughter of actress June Lockhart (best known for her role as June Robinson on Lost In Space), and was a fairly prominent guest artist on the television series of the Eighties. Aside from her recurring role on Battlestar Galactica, she appeared on Project: U.F.O., Tales of the Gold Monkey, Knight Rider, Voyagers, and guest starred in the Buck Rogers episode, "A Dream of Jennifer." According to the IMDb, in recent years, it appears she has been doing mostly voice work, including providing the voice of the U.S.S. Kelvin's computer in J.J. Abrams' Star Trek.
Like Lockhart, the attractive Spang appeared on lots of 70s and 80s television shows, including The Six Million Dollar Man, Isis, Man From Atlantis, and (like Lockhart) Project U.F.O. She seems to have pretty much retired from acting after 1984 to raise a family.
