Ahead of the release of Marvel Avengers Assemble featuring a whole rake of A List celebs, our good pal Roe McDermott headed over to London where she got the chance to catch up with stars of the highly anticipated summer blockbuster. Among the actors stepping into their superhero costumes was the ever affable Mark Ruffalo who plays The Hulk (leaving poor Mike seething with jealousy at home), Chris Hemsworth - otherwise known as Thor, Tom Hiddleston (Loki), Cobie Smulders (Agent Maria Hill) and Clark Gregg (Agent Phil Coulson). You can hear how she got on with them right here on entertainment.ie. BTW for the last one, while it sounds a bit like Roe's interviewing them from the next room, she isn't, technology just wasn't our friend that day. But sure you can forgive us that much ;)
