Before Marvel Studios released Iron Man in 2008 it was considered a risk. Few non-comic book readers knew of the genius billionaire playboy philanthropist before Robert Downey Jr. swaggered his way onto the big screen, and the rest is history. Risk has once again been the watchword in the build-up to Guardians of the Galaxy, the tenth film in Marvel’s ever-expanding cinematic universe. Granted, it’s a lot stranger than a man in a metal suit, but Marvel have since proven how adept they are at realising their characters on the big screen. Guardians is their reward for those previous nine pictures, and as directed by James Gunn it’s a delightfully fun ride.
