Albert Brooks talks about his having gone to five funerals. His brother Bob Einstein, who played Marty Funkhouser, died in 2019. Brooks' real name is Albert Einstein, but he uses a stage name for obvious reasons.
In the audition scenes, the casting directors are played by Allison Jones and Ben Harris, who are also the actual casting directors for this episode.
Normally, at the end of every episode, the theme song "Frolic" starts playing, and the show fades to black with the end credits rolling. In this episode, Larry and Albert Brooks go to a live concert with the song being played by a full orchestra (with a pan to the sheet music and the song's name). Larry and Albert are seen eating and enjoying the music while the end credits roll.
