American Mary is a 2012 horror film staring Katherine Isabelle, and directed by the Soska Sisters. It focuses on a young surgery student, Mary Mason, with financial troubles, resorting to offering services as a masseuse at a strip club. But at her interview at the strip club, Mary is asked to performed surgery on an injured man, the reward being a large sum of cash. Soon, Mary begins to receive customers looking for extreme body modification, and her mind begins to unravel after betrayal from her medical school professor. The trauma forces her to quit and as the movie goes on she finds herself involved in the underground world of bod-mod, pushing the limits more and more.
Affably Evil: Mary herself becomes this, along with Billy and Lance.
American Title: Ironic considering it's a Canadian film. It does, however, take place in Seattle. Word of God however tells us that "American" stands for the fact that the main character is living a slightly morbid version of the American Dream.
Body Horror: The film introduces body modification as a form of torture, which Mary uses on Dr. Grant. She alters his genitals, sews his mouth shut, and chops off various limbs, and leaves him in suspension for days on end.
Ruby, Mary's first client, has her nipples cut off and her vagina sewn together.
Two twins wanted their left arms exchanged, and horns placed on their foreheads.
Ironic Echo: Mary to Dr. Grant - "Surgeons can't afford to make mistakes."
Jerk Ass: Dr. Walsh's Establishing Character Moment is asking Mary to deliver the bad news to a family that their father has just had a heart attack... and then to go back two seconds later and tell them that he has died. Regardless of any hard lessons he is trying to impart to his interns, this is incredibly insensitive to the patient's family.
Noodle Incident: Quite a few events are never explained, such as how Mary's first patient got injured (not that it's of much relevance anyway), and what Mary's grandmother said to her that prompted Mary to delete her from her contacts. However, when one listens to the audio commentary track on the DVD, one finds out that Mary's grandmother dies. Most people also think that Mary was going to be a stripper, which is lampshaded by Mary herself when she calls Dr. Grant out on his crap after the all-changing attack.
Red Baron: Mary picks up the suitably macabre nickname of "Bloody Mary" among the online body modification community.
Roaring Rampage of Revenge: Mary uses body modification on Dr. Grant and keeps him alive. He is left unable to call for help or run away.
Ruby's husband attacks Mary over his wife's surgery.
Tap on the Head: Defied. A security guard discovers Mary's torture chamber, punches her to the ground, and turns away to try and help her victim - Mary recovers almost immediately, surprises him from behind, and beats him to death.
To the Pain: Mary lists off the most common body modifications that she wishes to 'practice' on Dr. Grant.
Unresolved Sexual Tension: Billy repeatedly fantasizes about Mary, and kidnaps and beats Dr. Walshto death after he finds out what he and Dr Grant did to her. For her part, Mary shows almost complete indifference to Billy's advances (barring the very end, ironically right before she is murdered) but comes close to stabbing another girl after walking in on her sucking him off. "Showing" being the key word here, though, as she's literally incapable of showing her true self after everything that happened. The only one seeing a glimpse of the "real" Mary is Lance, the big thug, during the "milkshake scene".
