In addition to films, Valen has also appeared in various television series. In 1990, she guest starred in an episode of "Saved by the Bell" as the brand new school nurse at Bayside High, Jennifer. Before Nancy Valen was cast as Nurse Jennifer, supermodel Kathy Ireland was going to play the part. Ireland was however ultimately fired during rehearsals after a disappointing table read and a similarly disappointing dress rehearsal. “She must have dazzled us in the office, because I hired her on the spot,” recalled co-creator Peter Engel. Engel soon called Ireland’s manager to inform him that she couldn’t do the part.
