At the beginning of the movie, Robert Young's character tries to commit suicide by running his car engine in an enclosed garage. Then in flashback, the doctor says that he's concerned about Young's character's recurring bouts of depression. In real life, Young suffered from depression for decades, and tried to commit suicide in Westlake Village, CA in January 1991 by running a hose from his exhaust pipe into the interior of his car. Young called a tow truck to try to start his car. The driver noticed the hose, and contacted the police.

The failure of the original copyright holder to renew the film's copyright resulted in it falling into public domain, meaning that virtually anyone could duplicate and sell a VHS/DVD copy of the film. Therefore, many of the versions of this film available on the market are either severely (and usually badly) edited and/or of extremely poor quality, having been duped from second- or third-generation (or more) copies of the film.
