Portland Oregon is well known for its rainy winters. On the winter day that the real estate agent scene was shot, it was bright and sunny. The original line was changed from "I forgot my umbrella" to "I forgot my jacket" due to the lack of rain.
The name of the real estate agent, Regina Kobritz, is inspired by the character Mrs. Kobritz in John Carpenter's "The Fog". Writer/director J.T. Seaton always includes a character named "Kobritz" in his films.
