Dr. Jeff Meldrum is a full Professor of anatomy and anthropology and expert on foot morphology along with locomotion in primates.
Bill Munns has conducted film analysis with National Geographic showing the subject's proportions in the famous Patterson-Gimlin Bigfoot film do not match that of any known human. This is coupled with his experimental work trying to build a Bigfoot costume to match the look of the 1967 film, resulting in his co-authorship of a peer-reviewed paper with Meldrum showing that the film subject is consistent with real anatomy and not a Bigfoot suit. Munns studied film and worked for 35 years making monsters for films, museums, and wildlife exhibits, thus is also highly-qualified for the study they have done. Their conclusions cannot be dismissed.
