I looks like Mondo Macabro has done it again with this upcoming R1 NTSC DVD.
DVD Maniacs (see link below for site, no direct link to review currently available) has given a superlative review to Luigi Cozzi's giallo THE KILLER MUST KILL AGAIN.
Looks like it's chock full of extras too, including a commentary with the director and Pete Tombs, two interviews with the director, and a Mondo doc on Gialli (originally included on DEATH WALKS AT MIDNIGHT), plus biographies, still galleries, production notes, a trailer and alternate opening credits.
The only downside is that this review is two months and 16 days before street date. Now THAT is torture.
