The trailer of Joseph Gordon-Levitt-starrer 'The Walk' has been revealed.
The film, originally titled 'To Reach the Clouds', tells the true story of highwire walker Philippe Petit's walk between the twin towers of New York City's World Trade Centre, reported Entertainment Weekly.
'Back to the Future's Robert Zemeckis directs the biopic and Ben Kingsley also stars in it.
The story previously inspired 2008 documentary Man On Wire.
It was recently announced that Gordon-Levitt will play Edward Snowden in Oliver Stone and Moritz Borman's film about the CIA whistleblower.
Gordon-Levitt has been working with Neil Gaiman on the Sandman screenplay.
