The Prometheus star barely spoke the language when she left her homeland to take part in an international press tour to promote her 2009 Swedish movie The Girl with the Dragon Tattoo, so she watched hours of U.K. TV in a bid to master the basics.

During an interview on Graham Norton's British chat show, she told the host, "When I was going (on) the press tour for The Girl with the Dragon Tattoo it was a nightmare because I didn't understand what people were asking me, so I decided I need to find a way to make this language mine so I read all the time and watched TV - including your show. You could say you were my teacher."

The interview airs in the U.K. on Friday night (17Apr15).
