Gael Garcia Bernal on democracy and Hollywood

31 January 2013 Last updated at 01:47 GMT

Mexican actor Gael Garcia Bernal is best known for his roles in films such as The Motorcycle Diaries and Y Tu Mama Tambien.

His latest film, called No, is based on true events, when Chile's leader General Pinochet called for a referendum in 1988 over whether or not he should remain in power.

He spoke to the BBC's Emily Maitlis on Newsnight about democracy and the possibility of a referendum in the UK, and why he wouldn't rule out working in Hollywood.
