Some comments, made before by other posters but worthy of being repeated:
The comparsion between "Planet of the Apes" and PGF, so commonly made by footers is flawed because:
1. PoA "apes" were not intended to represent "real" apes. PoA apes were a metaphor, "humanized" apes, with human bodies. Other than making the actors walk a bit curved, there was no effort to recreate an "ape body". They used clothes!!!! Is Patty wearing any clothes? PoA focused on facial prosthetics that allowed the actors to express emotions. Pretty common issue nowdays, but a major breakthrough by then. So, let's repeat one more time to keep it clear for some- PoA "apes" were Hollywood state-of-the-art only when it comes to facial prosthetics.
2. Want to make a comparsion between Hollywood apes and Patty, check the "Africa Screams" gorilla (very similar to Patty and its from the 40s!), the 2001 hominids (despite the shaggy hair), and Star Trek's Mugato (yes, Star Trek the original series was a low-budget TV show, despite what some footers claim). Wanna see "compiant gaits" and some Patty-like footage? Check those films, and check also the "classic" Japanese B-movies (Kaiju movies, if you preffer) "Godzilla X King Kong" and "King King Escapes". Plenty of Patties there, specially when the camera is slightly out-of focus.
3. At last but not least, PoA and "Africa Screams", as well the other movies had long sequences with steady camera movments, razor sharp focus and close-ups. All of these allow the viewers to nitpick flaws in the costumes. And PGF... How long it is? The camera is steady? The focus is perfect? The subject was filmed from up close?
Sorry, but if you want to present evidence for bigfoot, you'll have to do better than this.
