Jeremy Richey is hosting M.I.A. On Region 1 DVD Tribute Month and asked for some other choices.
Allow me to note Trouble in Mind by Alan Rudolph. I have little to say that isn't in Roger Ebert's review. I will note that the performance by Divine as Hilly Blue is sublime, and only shows the shame that Divine didn't live to work in more movies outside the John Waters oeuvre.
If You Meet Sartana Pray for Your Death by Gianfranco Parolini. Frankly, the whole official Sartana series should be put out in a nice box set. They're fun, slightly twisted, wholly James Bond influenced Spaghetti Westerns that could totally find an audience among genre fans.
Golden Swallow by Chang Cheh. Come Drink With Me is available now from Dragon Dynasty, so perhaps this sequel is in the works.
