The part of Roger McGrath is taken over by Vondie Curtis-Hall. A clip from the "previously on E.R." opener, showing Roger punching Dr. Benton from episode 7.22 "Rampage," was edited to replace the actor.

Eriq La Salle and Vondie Curtis-Hall both appeared in the 1988 Eddie Murphy comedy "Coming to America". La Salle played Darryl, the rich boyfriend of Murphy's love interest and Curtis-Hall had a brief scene as a stadium worker from Zumunda who excitedly recognizes Murphy as the Prince. They don't share dialogue but both of them do share a small amount of time on screen.
