Lisa, Lisa

Leslie Lee had done some modeling before playing her only lead role as Lisa in this film. She later refused to be interviewed for a special feature in the official releases of the home video versions of it on DVD, Blu-ray and 4K UHD Blu-ray by Severin Films on December 15, 2015.

When Lomax is burning holes in some clothes with his lighted cigar, the number of holes, the position of his body, and the position of the clothes are all not synchronized between shots.

For the film's original theatrical release in the UK (under the title "California Axe Massacre"), cuts were made both to a straight razor-slashing during a rape scene in it and another scene in it where Aubrey is beaten to death, and heavy cuts were also made to an infamous scene in it where a female cashier is shot at over her head and splashed with tomato ketchup; as a result of this, the film later found itself on the Director of Public Persecutions' (DPP) official list of "video nasties" in the 1980s. It was eventually first released on home video in the UK in 1999 on the Exploited video label under its original U.S. theatrical title of "Axe", but it still received 19 seconds of cuts to the previously mentioned straight razor-slashing scene. The BBFC said that they would have passed it uncut, but previous illegal distribution of the uncut version of it had led to a prosecution under Section 3 of the Obscene Publications Act (which was the same reason that both of the horror films Blood Feast (1963) and The House by the Cemetery (1981) were also slightly cut for their releases on home video in the UK). All of the cuts that had been made to it before were finally, completely restored to it for its second release on home video in the UK in 2006 on the ILC Prime video label, and this time it was released both uncut and again under its original U.S. theatrical title of "Axe".
