Step Up‘s Channing Tatum will star in a movie adaption of David Morrell’s best-selling thriller The Brotherhood of the Rose, Variety reports. The novel revolves around two orphans, trained by their CIA operative foster-dad to be assassins, who reunite when they separately find themselves as targets and wonder why. Tatum clearly enjoys life under the gun: He costars in July’s Michael Man-directed gangster flick Public Enemies opposite Johnny Depp and Christian Bale, and in August’s G.I. Joe: The Rise of Cobra.
