UK version is cut by 28 sec. to remove "dangerous imitable technique" during the scene where Alex attempts to kill Michael by connecting the car lights to the petrol tank.
The Australian theatrical release was cut to secure an M rating. Much of the sex tape sequence, the discovery of Claire's body and the sequence where Alex tries to blow up Michael's car were cut. These sequences were fully restored for the R rated video release and, oddly enough, the M rated DVD release.
