Part of what makes Airplane! so funny is that they had a number of well-known, established “serious” actors – Leslie Nielsen, Robert Stack, Peter Graves, Lloyd Bridges – in an over-the-top comedy; most of them played to their serious personas through deadpan deliveries of their funny lines.
Nielsen, in particular, relished being able to finally do comedy, and most of his roles from that point forward were in comedies.
I feel like I’ve seen Christopher Lloyd in a number of “eccentric egghead” cameos as nods to his Doc Brown character… I just can’t think of any specifics.
I don’t know if it counts, but I remember when he hosted SNL and he spoke about his career. “I used to be a dramatic actor who said unfunny things in an unfunny way. Now I’m a comedic actor who says unfunny things in an unfunny way.”
Ok, to sum all that up…Happy Days started as a Love American Style skit…Fonzie, Shirley (sorta) and Richie were all inspired by movie characters and sort of ported over.
And thats not even getting into how Mork was set in present time but initially was a dream (?) of Richies and what even happened to Chuck??
Oh and i see to make things even weirder, the same artist, Mort Drucker, drew the American Graffiti poster AND the Mad Magazine parody American Confetti.
In the musical version (it was awful and never made it to Broadway), the point was brought up and Howard just said, “We don’t talk about him.” It was the funniest line in the show.
