This film has no opening credits, except for the title itself. All throughout the entire film, immediately after a character is killed, the screen cuts to black, and the character's name, and nickname, is displayed.
SPOILER: The character names in the credits supposedly vanish in 'order of disappearance,' but the order is not correct and there are some which vanish together but they do not disappear together. The actual order of disappearance is: Kyle, Coroner & Det. Osgard, Dante (although he is listed dead later), Speedo, Limbo, Grace, Santa, Waitress, Simon, The Eskimo, Brock, Ahn, Dexter, Sly, Minya, Bone, Aya, Resort Clerk, Chuck, Mustang, Thorpe & Shiv & War Dog & Windex & Smoke (plus 7 more), Ryan, Dash, Gipsky, Viking, Avalanche, White Bull & Nels.
