Empire: You could, of course, call the Marvel Cinematic Universe the House That RDJ Built. Without Robert Downey Jr. blazing a trail as Tony Stark in the original Iron Man back in 2008, chances are the MCU would have spluttered and died long before Avengers: Age Of Ultron was a glint in Joss Whedon’s eye. So it makes sense that the second Avengers movie revolves around Stark, with Tony’s well-intentioned plan to ease the pressure on his super-friends by creating Ultron, a global AI police force, going somewhat awry. When the virtually unstoppable Ultron becomes self-aware and declares humanity personae non grata, it’s up to a guilt-ridden Tony to go toe-to-toe with his deranged creation. The effect this will have on the generally happy-go-lucky Stark will be fascinating, given that Downey is about to start work on Captain America: Civil War, which will pit the billionaire genius playboy philanthropist against Chris Evans’ walking flag, Steve Rogers. Is Tony about to become the villain?
