花絮 Trivia ：

The filming was so secluded, intense, and laborious that the last 20 minutes were shot with only the director and three cast members present. When off-screen the cast operated the boom mic and assisted with the camera work.

The barn that acted as the sound-stage was not air conditioned or heated and had only one door. On the first day of shooting it was over 100 degrees, on the last it was below 0.

The motel room set stayed erected for one year while the director cut the film for the purposes of re-shoots.

There is a single cut in the film from a wide-shot to a close-up of two characters that was filmed a year apart.

Sympathy was filmed entirely in one room. The set, structurally modeled after Room 1 in the Bates Motel, was constructed inside a barn in the middle of a corn field in Indiana.

While cutting the film, director/editor Andrew Moorman worked as a camera operator at Universal Studios Theme Park in Hollywood. He would often sneak down to the lower lot and eat his lunch in the famed Bates Motel set for inspiration.

Another example of how digital filmmaking has changed the way movies are made: the visual effects artist for the film volunteered his efforts via a posting on the internet and received all the digital clips from an FTP site. He applied the effects in a matter of days and would then return them, where they were re-inserted in the final edit, and burned to DVD. This person has never met the cast and crew and only spoke with the director once over the phone.
