Scared of heights? You might want to spend the weekend with Matt Damon on Mars than with Joseph Gordon-Levitt 1,300 feet above New York City.

Social media is buzzing about "The Walk," the new thriller from Robert Zemeckis chronicling daredevil Philippe Petit's 1974 crossing on a tightrope between the Twin Towers of the World Trade Center. According to early audience reactions, the film is excellent — but with one small caveat: if you suffer from vertigo, it could make you nauseous.

The last 20 minutes of the film focusing on Petit's highwire stunt is apparently the biggest culprit, with Denise Widman, board director of the Boston Jewish film festival, telling the New York Post: "I felt a little bit queasy. I felt nervous. It was a tingling sensation and some anxiety."

According to director Zemeckis, giving the audience a stomach-churning taste of what Petit experienced was exactly his intention. "[The goal] was to evoke the feeling of vertigo," he said earlier at a press conference. "We worked really hard to put those audiences up on those towers and on the wire.”

On that note, maybe it's best to grab dinner after the movie.
