Lorne Michaels asked all still-alive past cast members and guest stars to return for the special. However, not of all past still-alive cast members and guest stars did not appear in this special. The most notorious absence was O.J. Simpson.

Dana Carvey could not attend, but did record a new "Where are they now" spoof with Kevin Nealon as Hans and Franz. However, when the show ran late this sketch was cut. It was first broadcast on 16 October 1999, during an episode of SNL hosted by Heather Graham. The Hanz and Franz skit is still included on the DVD of the 25th Anniversary.
