The song "Let it snow, let it snow, let it snow" by 'Vaughn Monroe (I)' plays in Samantha's car radio. It also featured at the end of Die Hard 2 also directed by Renny Harlin.
The ice skating scene was scripted to end with Samantha performing a double-axel flip and simultaneously firing over her upside-down head.

One of the movie's original locations was a historic, grand hotel in Muskoka, Ontario, Canada - the 100-year-old Windermere House. During filming, however, the hotel caught fire and burned to the ground. The heat from the film lights were initially blamed for causing the blaze, but it was never proven that the lights started the fire.
The resort Windemere House in the Muskoka region of Ontario, Canada burned down while filming scenes there. Production company had to rework the scenes in Collingwood, Ontario. Windemere House has since been rebuilt.
