 SPOILER: There were two alternate endings filmed. Both are available  on the DVD. One had Hannah and Selena taking Jim to a hospital to  try to treat his gunshot wound, but they are unsuccessful and he  dies. They leave together. This is the one that was put after the  credits on some US prints, and when the film is shown on UK  television. Another ending was filmed that was pretty much like the  theatrical ending, but with a rooster instead of Jim. A third  alternate ending was written, but not filmed. It broke off right  after Frank becomes infected. In this version the military didnt  show up and Jim captured Frank alive and took him to the lab where  Rage was developed. A man who has barricaded himself in says Rage  can be cured by total blood replacement. Jim is a compatible donor,  so he swaps blood with Frank, who is cured while he becomes  infected. This was dropped because it didnt make sense as there was  no way they could completely remove all of Franks old blood. This  is presented on the DVD as narrated storyboards.
