This is based off of a true story. On August 7th 1974 somebody illegally secured a wire across the tops of the two main towers of the World Trade Center, and walked across. Of course news helicopters covered it and the footage along with interviews have been put into a documentary called "Man on Wire", perhaps a pun of the Denzel Washington movie "Man on Fire", but this clearly has nothing else in common with that movie.. Anyway, here it is: Apple - Trailers - Man On Wire - Trailer Quite impressive considering he had nothing securing him to the wire. One slip and he would have fallen to his death. I'm somewhat surprised I haven't ever heard of this event but it didn't take place in my lifetime either.
