There was a fourth ending shot, but subsequently dropped from the film due to the fact that director Lynn did not like or approve of it. Shots of this ending are included in the movie storybook. It had Wadsworth as the solo killer of the bunch, explaining that he killed everyone out of the need for perfection in the world, that all of life's consistencies were not good enough, and further tells the six 'victims' that he has poisoned the champagne he served and unless they find an antidote in three hours, they'll die. Police show up soon enough and trap Wadsworth, but not for long. He gets away from the chief and leaves, locking all the people in the mansion. But as he steals a police car, he notices a 'smell' (the dog dropping smell from the beginning of the film) and realizes the Doberman from earlier is now in the police car, and it lunges for him. The police car crashes, and Wadsworth is dead. This implies that the others got out okay now that the windows were not guarded by the Doberman any longer.
Three different endings exist for this movie, each with a different person being the killer. In theaters, only one of the endings was shown. Television and rental versions include all of the endings.
In some television broadcasts of the movie, the "drawing lots" scene in the kitchen is cut out. The scene goes from the decision to split up and cuts directly to where the pairs go to search the house.
There is a very large cut in the film when aired on Comedy Central and the Fox Family Network. When Green and Yvette stand at the bottom of the stairs and decide who is to go first, there are a number of scenes showing the other guests looking throughout the house before going back to Yvette and Green, where she says "Go on! I'll be right behind you!" This is how it is found in the theatrical version. On the television version, the scene of the two deciding who is to go first and the the "Go on!" scene are joined together, making one scene. All of the scenes in between are edited out. Also edited out is a scene of Scarlet and Mustard in the Billiard room, and a shot where Mrs White is in a darkened room saying "Are you in here? I'm coming"
The DVD version allows viewers to watch the original "A", "B", and "C" endings by themselves (chosen randomly by the DVD player), or to watch the three endings stitched together as on TV and VHS.
