Braindead, released as Dead Alive in North America, is a 1992 New Zealand zombie exploitation film co-written and directed by Peter Jackson.
Written by Jackson with his partner Fran Walsh and Stephen Sinclair, the film was a commercial failure at the time of its release, but has since gained a cult status following Jackson's fame with The Lord of the Rings trilogy, receiving positive reviews from contemporary critics. The film is widely considered to be one of the goriest films ever made.
The "Sumatran Rat-Monkey" is a hybrid creature that, "according to legend", resulted from the rape of tree monkeys on Skull Island by plague-carrying rats. Stewart, an explorer returning from the depths of the island with his team, is carrying a rat-monkey in a cage and is stopped by fierce warrior natives that demand the return of the monkey.
