For anyone who has seen Man On Wire, the documentary directed so adroitly by The Theory Of Everything's James Marsh, you will already be familiar with tightrope maverick and all-round daredevil Petite Philippe and his World Trade Centre spanning exploits in 1974.
Giving the death-defying feat a fresh big-screen spin is Zemeckis's The Walk, starring Joseph Gordon-Levitt (Looper) as Philippe.
Like Marsh's documentary, Zemeckis' film seems likely to pitch the yarn as a kind of heist thriller by other means. "He wasn't trying to steal money or sell plutonium," says the director, who interviewed Petit for hours, adapting the script with Christopher Browne from the performance artist's memoir To Reach The Clouds: My High Wire Walk Between The Twin Towers. "He was just trying to create performance art. And he created this beautiful, human moment that changed the way we looked at the towers."
Interestingly the film is set to be shown in 3D and IMAX, a combination that surely threatens to leave anyone of a sensitive disposition a gibbering wreck on the floor.
Starring alongside Gordon-Levitt are Charlotte Le Bon (Mood Indigo), James Badge Dale (World War Z), Ben Schwartz (Runner Runner) and Ben Kingsley (Hugo). The Walk is scheduled to arrive here on 2 October 2015. And remember, don't look down.
