Below is an edited version of the infamous scene from Georges Franju's poetic horror film Eyes Without a Face (1960), in which plastic surgeon Doctor Genessier removes a woman's face to replace that of his disfigured daughter. You don't actually see that much, and the special effects are not convincing today, but nonetheless not recommended for the squeamish.
The cover of the Criterion DVD release of this film (left) is a typical example of the inspired approach to design used by this company, who always pay careful attention to the packaging and presentation of their releases.
The film is an obvious reference for the character of Cuckoo in Five Wounds, although in fact I did not see it until after I had conceived of the character.
My favourite scene in Eyes Without a Face is not the one excerpted in the clip above, but rather the subsequent montage that shows the transplanted face rotting as the recipient rejects the skin graft (which is also apropos to the themes of Five Wounds, but to the character of Crow rather than that of Cuckoo). Unfortunately I couldn't find that clip online.
Bonus inspiration points for the fact that a character is eaten by dogs in the film's finale.
