Barring the fact that The Secret Life of Walter Mitty makes over $100 on in its second weekend, it's (nearly) safe to say that 2013's biggest surprises at the box office are behind us. And boy, were there some huge shockers in store for audiences this past twelve months. While most of the big tent pole pictures performed as suspected, it was the smaller budget movies that made a real impression on moviegoers this year. Now, we take a look at 13 movies that no one thought too much about before their release. Some people thought a couple would bomb all together (hello, World War Z). It's the 13 Biggest Box Offices Surprises of 2013



Tagline: Don't Let Go. Why it Surprised Us: With a simple premise (two astronauts lost in the dark recesses of space), Gravity became the water cooler conversation starter of 2013, and has the honor of being one of only two movies to hold down three #1 weekends in a row. No small feat in what has become an overcrowded market place that sees tons of new releases jockeying for position every single given week of the year. With a hefty $145 million price tag, this sci-fi thriller certainly was a gamble for Warner Bros., especially since it had to rest solely on the charm of its two leading actors. Luckily, they had the biggest box office draw at their disposal in Sandra Bullock (she's on this list twice, by the way), and George Clooney, who isn't too shabby either. While director Alfonso Cuarón has directed one of the more beloved installments of the Harry Potter franchise with Prisoner of Azkaban, he isn't exactly a household name when it comes to crowd-pleasing blockbusters. That all changed with this, a movie that was greatly helped by critics. It is one of the biggest moneymakers of the year. It is the sixth highest grossing movie of the year. And best part of all, no one saw it coming! Budget: $100 million. Domestic Gross: $252.9 million. Worldwide Earnings: $642.2 million. Money in the Bank: $542.2 million.
