Austrailia:

Body Melt (1993)
This is kind of the Down Under answer to Street Trash - its plot (about an experimental dietary supplement with ghastly side-effects) is just an excuse to have scene after scene of people melting and mutating in a orgy of old-school FX.

The Netherlands:

The Johnsons (1992)
Dutch director Rudolf van den Berg’s film is one of the strangest genre films of the ’90s. It begins with an adolescent girl experiencing intense nightmares about being raped by seven bald psychopaths. With the help of her photographer mother and an anthropology professor they begin to unravel the mystery, which involves the rebirth of the evil South American God Xangadix by means too terrible to mention. With so much going on, The Johnsons is a little overstuffed but still awesome.

Canada:

The Reflecting Skin (1990)
Kind of a forgotten film in the annals of Canadian horror but one of the better “artsy” horror films, as directed by Philip Ridley (whatever happened to him, by the way?). Genuinely sad, weird coming-of-age story that has a sort of David Lynch vibe.

Hong Kong:

The Seventh Curse (1986)
Chow Yun-Fat appears as a secondary character in this wild Indiana Jones-style adventure directed by Lam Ngai Kai (The Story of Ricky) that’s bursting with mysticism and monsters. It’s a ridiculous but yet hard not to love movie.

And thanks to Jeff who posted above me, I also want to see The Johnsons and The Seventh Curse. I love The Reflecting Skin and I really wish Philip Ridley would make more films too.
