In an interview with MTV, Kurtzman said about the genesis of the flick: "We took some time to think about what were the sequels that we loved, and why did we love them. The Empire Strikes Back, Superman II, Aliens, Terminator 2 - all amazing movies ... Wrath of Khan, what do those movies have in common?" Answering his own question, he said: "They stand on their own - you don't have to see anything that came before for that movie to be a great movie. And there was always some massive emotional test that the lead character had to go through and come out the other side of." Another aspect of Revenge of the Fallen they liken to these titles is the hardship endured by the lead protagonists: "The good guys get their asses kicked," Kurtzman said. "Superman gives up his powers for love, or Kirk loses Spock ... you need that darker idea that tests your hero, to really make the sequel sing." Unlike The Wrath of Khan or Empire, however, Revenge won't directly set up a necessary threequel. Orci said: "We wanted this movie to stand on its own - even though things are set up, it's not exactly a cliff-hanger. You're going to get the whole movie." We'll have to see for ourselves whether the movie will live up to these classics when it's released worldwide at the end of June.
