Hackett starred as the title character on NBC-TV's "Stanley", a 1956–57 situation comedy which ran for 19 weeks on Monday evenings at 8:30 pm ET. The half-hour series also featured a young Carol Burnett and the voice of Paul Lynde. The Max Liebman produced program aired live before a studio audience and was one of the last sitcoms from New York to do so. "Stanley" revolved around the adventures of the titular character (Hackett) as the operator of a newsstand in a posh New York City hotel.
