As long as fairytales exist, Hollywood will never be out of ideas. At least that's the takeaway from the trailer for 'Jack the Giant Killer,' which reimagines classic folklore 'Jack the Giant Killer' -- and 'Jack and the Beanstalk' -- into a slam-bam action spectacle with monstrous giants, flaming trees, and a handful of beans ... "that can change the world as we know it." OK, beans. You do that. The charming Nicholas Hoult ('X-Men: First Class') plays the titular Jack, while Bill Nighy, Ian McShane and Ewan McGregor provide support -- though don't blink or you might miss them in the trailer. Seemingly part 'Jurassic Park,' part 'Your Highness,' part 'Mirror Mirror,' 'Jack the Giant Killer' arrives in theaters in June 2012. Bryan Singer ('X-Men,' 'Superman Returns') directs.
