Believe it or not, selecting the 15 biggest box office bombs of 2013 is not an exact science. Studios withhold precise budgetary figures and marketing costs, and even a film that crashes and burns in its initial U.S. release can play like gangbusters overseas or in the ancillary market. A movie's full cost is much more than just its production budget, as most big summer blockbusters (or would-be blockbusters) spend anywhere between $50 million and $100 million on marketing. Plus, keep in mind that studios only keep roughly half of a film's box office take. Other avenues (DVD, streaming, OnDemand, traditional TV sales) help make up the difference, but they aren't what they were a year ago, let alone ten years ago. With all that in mind, we've compiled a list of fifteen films from 2013 which can only be classified as box office bombs.
