The Roxy Bar and Screen is perhaps one of London's best-kept secrets. Tucked away behind thick red curtains, the screening room has something of a speakeasy feel about it – expect comfy couches, cosy armchairs, leather sofas, tables and barstool all set in front of the big screen. Your ticket also includes any main dish from the Roxy menu before you tuck into the main event. For this one, get ready for the 2015 American action thriller Blackhat, co-written, co-produced and directed by Michael Mann. Set within the world of global cybercrime, Blackhat follows a furloughed convict, played by Chris Hemsworth, and his American and Chinese partners as they hunt a high-level crime network from Chicago to Los Angeles to Hong Kong to Jakarta. Expect thrills and spills in an old-fashioned thriller with a bit of byte. "Unlike most directors, style is hardly a side dish with Michael Mann - it’s the main entrée." – Time Out "Technology may have changed, cyber-crime may be all the rage, but the narrative song remains the same in films like this." – LA Times Over 18s only. Certificate: 15. Valid ID required. Runtime: 2 hours 10 minutes. Dress code: smart casual.
