When Kevin Spacey hosted the show in 1997, one set of sketches spoofed the screen tests for Star Wars: Episode IV - A New Hope (1977), which included Kevin Spacey playing Christopher Walken trying out for the role of Han Solo. Christopher Walken really was considered for that role, before Harrison Ford was chosen.
The Star Wars screen tests from this episode (approximately 4 minutes) are included as the second segment of the Star Wars Spoofs (2011) special feature on Bonus Disc 3 of the Star Wars The Complete Saga bluray release in 2011.
Kevin Spacey plays Al Pacino during the Joe Pesci Show sketch, and plugs Pacino's documentary Looking for Richard (1996) in which Spacey also appears.
