When "Adventures of Superman" came to television in 1951, veteran movie actors George Reeves and Phyllis Coates took the leading roles for the first season. By the time the series found a sponsor and a network time slot, Coates had committed herself to another production, so the producers called on Neill to reprise her role as Lois. She continued on the series for five seasons until it left the air in 1958. In 1954 she also appeared in "Stamp Day for Superman" which was produced by Superman Inc. for the United States Department of the Treasury to promote the purchase of U.S.Savings Bonds. It was only distributed in schools to educate children about the bond program. She was scheduled to appear in the seventh season with co-star Jack Larson in 1960, but after Reeves's tragic and sudden death, the seventh season was canceled, officially ending the show. While Phyllis Coates generally distanced herself from the role, Neill embraced her association with Lois Lane, giving frequent talks on college campuses during the 1970s, when interest in the series was revived, endearing herself to audiences with her warmth and humor.
