The second Pat Higgins film released was actually his third. Pat shot HellBride and KillerKiller back-to-back in that order but this was released in 2007 whereas HellBride didn't come out until 2009 so falls outside the scope of the book.
This is my second favourite of Pat's four solo features, a taut, simple story of psychos being picked off one by one in some sort of supernatural limbo. Or something.
In other good news, I discovered that I had the wrong release date for two films I haven't yet written up, reducing my total from 113 to 111 so there's now only 34 to go.
