The film was released 3 different times (ntsc format)on dvd and each disc features a different aspect ratio. The first dvd edition from Critical mass (25th anniversary) used the proper full frame format (the film was shot this way). The second dvd release from Critical Mass (listed as being just a special edition) uses a 1:75:1 aspect ratio, it was also noted that director Bob Clark approved of this ratio. The latest dvd special edition from Critical Mass (December, 2006) uses an over-matted 1:85:1 ratio. This 1:85:1 over matted ratio also appeared on the special edition laserdisc that was released by Warner bros a few years back
The UK cinema version was cut by the BBFC to remove all instances of the word 'cunt' from the obscene phone calls, together with some of the other crude sexual references during the same scene. The 2003 Tartan DVD release restores all previous cuts.
