A few corrections:
“Edit: What our panel didn’t know is that the woman is played by” is incomplete. Presumably you meant to say June Cleaver and/or Barbara Billingsley.
According to IMDB, Jimmy Walker Jr. and Jimmie Walker are two different actors who both happen to be named James Walker Jr. It’s the latter, much more famous Jimmie Walker who has the cameo. Additionally, his previous role was playing a passenger in Airport ’79.
When the flight crew lean in, smiling, as Randy begins strumming the guitar, the guy who looks directly at the camera is the flight engineer. Kareem– I mean, Roger Murdock is the co-pilot.
You’re damn fools for having the“‘Roger.’ ‘Huh?’” sequence so low on the list. That was one of the best scenes in the movie!
