Several other people were also involved with the production of the ceremony. Bill Conti served as musical director and conductor for the event. Production designer Roy Christopher designed a new stage for the ceremony which prominently featured a proscenium which was designed to resemble the iris of a camera. Moreover, Christopher commented that the iris motif was inspired by the iris shot prominently featured in several comedic films and shorts. Dancer Debbie Allen choreographed "The Lion King" musical number. Actors Alec Baldwin, Jack Lemmon, Steve Martin, and Rosie O'Donnell participated in a pre-taped comedic sketch lampooning auditions for a role in "Cabin Boy", the film in which Letterman made his film acting debut.
