Trivia, insights & behind the scenes
The ship was a real decommissioned vessel that had actually been a floating Nazi prison during WWII, which the cast found deeply unsettling during filming.
This film is peak 'Canuxploitation' — Canadian tax shelter horror that somehow attracted legitimate Hollywood stars for quick paychecks. George Kennedy reportedly took the role specifically because he wanted a free trip to Quebec.
