There were 8 episodes of a 1985 TV show where Joe Pesci is an ex-cop trying to be an actor. Also stars Fred Williamson, Victoria Jackson, George Kennedy, and for only 8 episodes it has a heck of a list of (what I assume are) guest stars. It's a TV show, but you've done those before, and this feels like peak riffing material: https://www.imdb.com/title/tt0088530/?fbclid=IwAR2Eenuxq7XS0DmMshbi6XlqyH2_B5l6IIcqKJvhG1QBmRVwYhzSEs-XnCc
