Absolutely. Both stand as "undebunked". The PGF is older than the Marx film but Marx Limpy remains as having not been debunked. Who knows how many have tried and failed to debunk it and it also doesn't matter how many people in the world think that it is a hoax. Only the debunking counts, right? Isn't that what you are arguing for with the PGF?
How would you debunk Limpy? You know that you can't look for and point out things like seams, joiners, cuffs, fake fur, etc. That is because the boys and girls at BFF have already spent years amassing hundreds of photos of gorillas and chimps whose bodies show things that look just like costume "flaws". If you can find a picture of a living chimp with fur that looks like pantleg cuffs then you can never debunk any costume that shows a pant cuff even if it actually is a pant cuff. Yes, the Bigfooters have already sealed off any chance of debunking a picture or film based on seeing features of a suit. They already found a picture of a live gorilla showing that bit that you think is revealing a costumed man.
You can't debunk Limpy. Don't even try.
