Like many other movies of the Dimension Extreme series, Argento's final chapter of his Mother-trilogy had been released in two versions in the US, too: in a censored R-rated version and in an uncensored original version as an unrated DVD. As this is an Italian movie, there are no extraordinary cuts, just some for censorship reasons. The R-rated version is even heavier cut than similar censored versions, due to some cuts of erotic material.
