The suitcase full of shoes found in the Riverside Motel in Silent Hill: Origins is a reference to Phillip Gerard's motel room in Twin Peaks. Gerard (aka the One-Armed Man) was a shoe salesmen and kept his wares in a suitcase in his motel room.
A Twin Peaks Season 1 DVD set can be seen on Victor's entertainment center. Additionally, one of Karen's voice-mail messages, from "Mr. Lynch," is delivered as a Gordon Cole imitation by director Stuart Wahlin.
