During the TIE fighter attack on the Millennium Falcon in Blue Harvest, Nielsen's character, Dr. Rumack appears and says "I just wanted to say 'Good luck' and we're all counting on you". This is a reference to the 1980 comedy Airplane!. The audio of him saying it is from the movie as Nielsen was unavailable to reprise his role and the crew did not want an impersonator to read the line.
