Here's why theatre-goers are throwing up during screenings of ‘The Walk’

Robert Zemeckis' new movie is making people puke, and it's not because of the violence or gore in the movie, it's the height.The Back to the Future and Forrest Gump director's latest, The Walk recounts the story of Philippe Petit's walk across the Twin Towers of the World Trade Center in 1974.[caption id="attachment_2450372" align="alignleft" width="380"] Screengrab from the trailer. YouTube[/caption]The film recreates Petit's walk across the two towers at the height of 1,362 feet on a wire. And did we mention the movie is in 3D.The effects are proving too much for some people and giving them a sense of vertigo.A reporter told Zemeckis and his cast at the press conference that the scenes above the towers made him feel a little sick, reports Business Insider.Later, journalist Mark Harris confirmed the reports of someone vomiting at the theater:The events of the film have been previously been recounted in the Oscar-winning 2008 documentary Man on Wire, but Zemeckis' version recreates the sequences from Petit's point of view, and hence, the vertigo.The film, starring Joseph Gordon-Levitt as Petit will be out on 9 October.
