I a big fan of Martino's works.
DVD's I have are:
The Strange Vice of Mrs. Wardh
Case of the Scorpion's Tail
All the Colours of the Dark
Your Vice Is a Locked Room and Only I Have the Key
Giovannona Long-Thigh
Torso
Gambling City
Mannaja: A Man Called Blade
The Mountain of the Cannibal God
Big Alligator River
I'm hoping more of his 80's action flicks find their way to DVD soon!
