When this movie was reviewed by Joel Siegel, on WABC-TV Eyewitness News, New York City, in September 1986, a few seconds of a clip of Sigourney Weaver, topless on the exercise bike, was accidentally shown.
Filmed before "Aliens (1986)," but released afterwards. Production on this movie was running behind, and ultimately, Sigourney Weaver ended up with only a couple of days off between the completion of her work on this movie and starting shooting on "Aliens."
One of three filmed productions from 1986 adapted from a story, or novel, by Paul Theroux. The others being "The Mosquito Coast (1986)" and "Christmas Snow (1986)."
Paul Theroux's personal website summarizes the source book "Half Moon Street" (1984), of which this movie was an adaptation of the first novella called "Doctor Slaughter": "Two brilliant short novels on the theme of a double life. Although they are worlds apart in scene and character, both are full of a kind of eerie menace that lies just beneath the outward events."
