Forget the Batman movie... Go see Man on Wire.
It is a documentary on the true story of a French wirewalker who, in the mid 1970s, conspired with friends to rig a wire across the World Trade Center towers (the method used is very Batman-esque). Philippe Petit then walked across the wire, over a 1/4 mile up.
The film is a spellbinding thriller. We know how it turns out and yet one fears for this strange pixie. Just look at the photo on the website above. Mon dieu!
It can also be viewed as a tribute to the WTC: it does not mention the fate of the towers, and yet of course the 800 lb gorilla is sitting next to you the entire time.
