Channing Tatum: He danced to fame in 2006’s “Step Up,” then started “Fighting” in 2009. “G.I. Joe: The Rise of Cobra” led to “Haywire” and action-comedy “21 Jump Street.” This summer he’ll make terrorists die hard in “White House Down” — and then he’ll take action out of this world in the Wachowski’s “Jupiter Ascending.”
