At the urging of his wife Lotte, frustrated street puppeteer Craig Schwartz takes a lowly filing job on the 7½th floor of a bizarre Manhattan office building and falls hopelessly in love with his remote co-worker Maxine. Then he discovers a boarded-up tunnel behind a filing cabinet that proves to be a portal into the mind of actor John Malkovich…

How does someone come up with such a brilliantly crazy idea?

Being John Malkovich is showing on Film4 tonight at 11.15pm
