Rabid is as good an example of this as any.

After a bad motorcyle accident, a young woman named Rose (Chambers) undergoes a reconstructive operation.

But the surgery leaves her with a deadly side effect: an insatiable craving for human blood, and a disgusting phallic-penis thing in her armpit which she uses to suck said blood from her unwilling victims.

Her penchant for blood then turns most of the people of Montreal into zombies.

Sound crazy? It is. And it's all utterly fascinating.

Cronenberg again explores his theme of bodily functions & organic mutations gone terribly awry.

Ex-porn star Marilyn Chambers delivers a surprisingly real performance.

The film is perfectly complemented by a cold, chilly Canadian atmosphere filled with dank yellow, green and tan '70s hues. Wonderful!

(Children be warned: there is an extremely disturbing scene in which a mall Santa Claus is accidentally shot.) Yes!
