The Human Centipede II (Full Sequence) (2011)

Factual error: In his crude attempt to replicate the Human Centipede surgical procedure, Martin employs several handyman tools, including a carpenter's staple gun (using T50 staples as sutures). Problem is, carpenter's staples would never join soft human body tissues, they'd pull right out with little effort (T50 staples only join to very solid base materials, such as wood). Martin's victims, hysterical as they were, could have freed themselves from the T50 staples almost immediately.
