The Walk - International Trailer (Official Teaser) - YouTube
The 2008 documentary Man on Wire already did a great job of telling the story of Philippe Petit's wire walk between the Twin Towers.
Still I am looking forward to The Walk which will be retelling the story as a feature film. Also it's good to have Robert Zemeckis doing another live action movie in period setting.
And I was curious to see how they incorporate sequences of the Twin Towers through CGI in the movie. Looks good so far.
Oh and Back to the Future gets mentioned in the trailer
