15 Minutes - Where'd the Chair Go?
Warning: if you haven't seen the movie, this will ruin some of it for you.
In the scene about two-thirds of the way through, Emil and his partner break into Eddie's apartment to kill him. They have Eddie securely duct-taped to a wooden chair as they taunt him. Somehow Eddie manages to stand up and starts attacking the men with the chair by running at them backwards. Emil then takes a knife, there's a struggle, and he stabs Eddie in the stomach. Eddie then falls to the floor and somehow manages to fall flat on his back. Where's the chair? This whole murder scene is videotaped by Emil's partner, and later in the movie, the videotape is aired on the fictional TV show "Top Story." In the video playback, after Eddie is stabbed in the stomach, he falls down, lands on his side, with the chair still securely duct-taped to his body.
None - you just need to watch the movie!
