3. "The Secret Life of Walter Mitty"
James Thurber's 1939 short story about a sad, middle-aged man with an amazing fantasy life was adapted into a movie with Danny Kaye in 1947, and it came close to getting remade with Jim Carrey in the title role nearly 50 years later. That project ultimately fell apart, but Ben Stiller picked up the pieces in 2013 for a new, contemporary adaptation. This time around, Mitty was working in the photo department of Life magazine when he was forced to travel to a distant corner of the world to track down a lost negative. Stiller played the lead role and directed the film, which grossed $188 million.
