I Stand Alone (1998)
A 30 second warning prior to the finale of the film was inspired by Castle's "Fright Break".
The prolouge showing the butcher's life up until the film starts, shown in various stills is a direct homage. Also, both films consist almost entirely of a disturbed man's inne thoughts.
