I don't think remembering is the problem. They're iconic enough that multiple generations know of them. There was even a short-lived revival about 10 years ago on CN.
With the Three Stooges, I can understand why it failed. Moe, Larry, and Curly were the Howards/Fine. No one can ever be them, not even in imitation. Plus, they're too fondly remembered. No one should ever try to be Mr. Bean, either.
As for the Laurel & Hardy biopic... it's a biopic. I'm sure it's remembered, but so what.
I just don't think I'll ever be in the mood to see a horror version of them. I was really hoping the Happytime Murders was going to be good, but I'm glad that wasn't with bonafide Muppets. I hope to never see an axe-wielding Gonzo.
I think the Banana Split gang was hosts of a Saturday morning show, that introduced short live action adventure shows and cartoons.
Liken making a movie on Elvira, who was a host of obscure horror movies.
With what's going on in Hollywood's creative world, ...there might be an Epic Sci-fi movie series on Commander Tom and his robot companion, Promo.
