Larson found the role of cub reporter Jimmy Olsen on "The Adventures of Superman" to be a handicap, because he became typecast as a naive young man. This caused him to do little acting after the show ended in 1958, and he turned to writing and production, with an output that included plays, a libretto, texts for classical music, and movies such as "The Baby Maker". In later years his attitude towards the Jimmy Olsen role warmed, as he focused more on the love people had for the character. Larson was always willing to sit for interviews about the "Superman" series and his connection to it, and began having a number of cameos that paid subtle tribute to his character and the series, including a 1991 episode of the TV series "Superboy", alongside Noel Neill, who played Lois Lane in "Adventures of Superman", and an episode of "" as an aged Jimmy Olsen in the episode "Brutal Youth", first broadcast on October 20, 1996.
