Physics in Film

Mission Impossible III is without a doubt an entertaining action movie and it fulfills its purpose in that way, but upon further analyzation of some questionable scenes we can see how realistic the physics in the movie are.  In the first scene I would like to look at, Ethan Hunt (Tom Cruise) infiltrates a heavily guarded skyscraper by swinging from a neighboring building successfully landing and thus completing the mission. The question posed from this scene is whether or not Hunt could have made the jump. Some key elements to recognize are the distance between the buildings and the length of the chord used in the jump. Neither of the quantities are specified in the film but with some research of the building heights its easy to assume the buildings in question are around 200 to 250 feet apart or 61 to 70 meters. I can assume that the chord used in the jump would have to be at least the length of the gap so given that estimation I assume the chord is about 70 meters. So theoreti...
