On a budget of $110 million, principal photography began in New York City on March 26, 2010. In May, scenes were filmed in Manhattan's SoHo neighborhood. That month, scenes were shot all night for five nights in a row at F.A.O. Schwartz toy store. Production was temporarily halted after a worker fell 30 feet from a set at the toy store on Fifth Avenue and 58th Street; he later recovered in a hospital. Other locations used for filming were Belvedere Castle, the Russian Tea Room, Rockefeller Center, and Brooklyn's Prospect Park. A two-thirds-scale replica of the Belvedere Castle was built with wooden grates as floors (to create additional contrast). Gargamel's dungeon under the Belvedere Castle, which included the "Smurfalator", was built on a soundstage. It took three months to build because some parts were hard to come by. Production eventually found the rare parts at garage sales, flea markets, on eBay and Craigslist.
