Almost immediately, Garry Marshall signed Walker for another series, "Blansky's Beauties". The main character of the series was introduced a week before the series premiere in an episode of the hit sitcom, "Happy Days". The show premiered on ABC-TV in February 1977 with Walker playing Nancy Blansky, den mother to a group of Las Vegas showgirls. It failed to find an audience and was cancelled in May 1977, giving Walker the unenviable distinction of being in two failed series in the same year. She returned to "Rhoda" at the beginning of the 1977–78 season (giving the show a much-needed boost in the ratings, which had fallen the previous year), and remained with the series for the rest of its run. During this time, she began directing, including episodes of "The Mary Tyler Moore Show", "Rhoda", "13 Queens Boulevard", and "Alice".
