Bryan Singer is getting his green light on Jack the Giant Killer, and he’s now figuring out who'll climb the vine and slay the oversized villain. I’m told it has become the role that young actors are circling. I've also heard that Singer's sweet on Aaron Johnson, who played the title role in Kick-Ass, and portrayed the young John Lennon in Nowhere Boy. Now, Johnson is hardly a lock; New Line is seeing a lot of other young actors as well. Production will begin this spring.
