Cinema is the most popular form of entertainment: there were more than 141,000 film shows with a total attendance exceeding 2,700,000 in 2014. Over the past two decades, numerous independent cinemas have closed and most shows are in shopping centre multiplexes. ''Odeon'' (not part of the Odeon Cinemas chain) shows exclusively European and independent American films, as well as 20th century classics. The Boyana Film studios was at the centre of a once-thriving domestic film industry, which declined significantly after 1990. Nu Image acquired the studios to upgrade them into Nu Boyana Film Studios, used to shoot scenes for a number of action movies like ''The Expendables 2'', ''Rambo: Last Blood'' and ''London Has Fallen''.
