I think of, for example, the Beverly Hillbillies movie. That was one of the all time great TV shows but the movie was pretty awful. I think the Miss Jane character was semi-OK (I think it was Lily Tomlin, no?) but the rest - well once you have the initial characters in your head everyone else comes up short.
Which is why 99% of Stooges fans don’t like the post-Curley Stooges shorts. Shemp, or the others may have been “good”, but they weren’t Curley. It’s an almost impossibly high bar.
Shemp Howard had the most viable film career outside of the Three Stooges. Moe appeared in a couple of films.
They almost reunited for Blazing Stewardesses but the Ritz Brothers ended up with the part (I think because of Larry’s failing health).
