Fast & Furious 6 was in development by February 2010 as the first film in the series to move away from the underground car-racing theme of the series' previous films which was considered to have placed a barrier on audience numbers. Pre-production had begun by April 2011, and principal photography began in London, England in July 2012. Filming locations also included the Canary Islands, Glasgow, and Los Angeles. The film was first released in the United Kingdom, on May 17, 2013, followed by an international release on May 24, 2013. The film has grossed over $780 million worldwide, making it number 50 on the all-time worldwide list of highest-grossing films, in unadjusted dollars, and the 6th highest-grossing film of 2013. A sequel was released on April 3, 2015.
