Ryan Gosling plays a Los Angeles police officer in his latest movie Gangster Squad.

The film follows the LAPD's battles with gangsters in the 1940s and 50s.

Talking to the BBC's Emma Jones, the actor reveals how he was inspired by Dick Tracy, how taking time out from acting helped him get in touch with his roles and why he hasn't let go of his musical roots.
