Often times, movies' popularity and success comes down to how well they performed at the Box Office - in other words, how much money did each film gross when it first premiered in theaters? Some films are so successful that they impressively make hundreds of millions of dollars. Most people might be able to identify the most popular and successful films from the past several decades, but it takes a real film buff to be able to guess which of the top films made the most money at the box office? Do you think you could really determine which movies made more money during the decade they first premiered, including the following pairs: Notorious or Meet Me in St. Louis, It's a Wonderful Life or Spellbound, Suspicion or Rebecca, Citizen Kane or Casablanca, Ben-Hur or Rear Window, Some Like It Hot or Cat on a Hot Tin Roof, Gentlemen Prefer Blondes or The Man Who Knew Too Much, Singin' in the Rain or To Catch a Thief, The Sound of Music or The Graduate, The Godfather or Rocky, E.T. The Extra-Terrestrial or Raiders of the Lost Ark, When Harry Met Sally or Steel Magnolias, and The Silence of the Lambs or Pulp Fiction.
