Originally released at 80 minutes; reissued in 1979 at 76 minutes, deleting the studio-imposed prologue and epilogue starring Whit Bissel and Richard Deacon.
Five cuts were made by the British censors on its initial release, mainly references to Burke and Hare, the original bodysnatchers. This cut print has been the only one available in the UK until 1998, when a complete widescreen version appeared on the budget video label 4-Front.
There is a colorized version by Republic Pictures 80 minutes in length.
When standard academy (1.33:1) prints were prepared, the opening credits were re-shot with the "superscope" logo deleted. This print was also used for the original television syndication prints and the early home video releases.
