Hopefully someone will do an in-depth interview with the Jung Brothers about their film influences. The violins and violence of Psycho is obvious. There is also a shot that is the reverse of the signature shot from the Thai horror film, Alone. In the earlier film, we see the surviving half of two conjoined twins, walking on the beach, looking back to see two sets of footprints. In Epitaph two married doctors are at the beach, but we see only one set of footprints. There is also a scene involving a snow globe, which may possibly be a deliberate nod to Citizen Kane. It is not simply the use of the globe, but how Kane's shifting narrative may have inspired the Jungs. In addition to the repetition of scenes, the film shifts into memories, dreams, and dreams within dreams.

It is not simply time that is played with, but space. This can be as simple as a young girl stepping into a room filled with white light. One of the more spectacular moments is a scene depicting the evolution of a relationship between the young intern Park and the woman of his dreams. As the camera moves forward, we see the lovers in as newlyweds, and as parents, with screen doors sliding open to reveal each new stage of the relationship, with a corresponding color scheme representing the changing seasons. It's a brief scene, but one that indicates a promise that the Jung Brothers may be among the more interesting young filmmakers in Korean cinema.
