WATCH: Joseph Gordon-Levitt in the Extended Trailer for The Walk

If you haven't heard of Phillippe Petit before, Joseph Gordon-Levitt's portrayal of the famed tightrope walker in The Walk will have you googling him excitedly.

In 1974 Petit hatched an intricate plan to place a tightrope between towers one and two of the World Trade Center. He refused to use a safety line and spanned the space between the twin skyscrapers with nothing but a balance pole.

The almost five-minute trailer is to promote the film's IMAX showings, and with sweeping views of the New York skyline and plunging glances from the tops of the towers, it might actually be worth the extra ticket price. Watch below.
