When you examine and compare costumes like that, it becomes evident that they aren't even close to the Patterson film. None of the fur contours to any of the muscle or sub-surface fats. Instead the fur drapes over and conceals the curvature of the muscle in the arms and legs, and masks the joints at the wrists, elbows, knees, and ankles. The wonderwoman gorilla suit looks just like the suits used to make the planet of the apes films, and shares similar characteristics, none of which are consistent with the Patterson film.

Who's to say Hollywood is the gold standard for monkey suits? They guys knew the video would be examined, so they did their best. It still looks like shit in HD.
