Can you guess the number of actors who have had three $100 million hits in the same calendar year?  The answer is one and, shocker, it's Channing Tatum.  In just six years, Tatum has gone from disrespected "Step Up" star to a force in the industry.  Tatum started 2012 with the romantic hit "The Vow" ($125 million), continued it with the comedy smash "21 Jump Street" ($138.4 million) and in June delivered the surprise summer profit center 'Magic Mike" ($113 million).  Tatum's star power is so bright now that Paramount Pictures purposely delayed the release of "G.I.Joe: Retaliation" at the last minute to allow for reshoots to include more of Tatum's character who originally was killed off in the first act (it's still unclear whether the new version of the movie finds Duke alive or dead). Three years ago, Tatum couldn't get a grade A project even sent his way.  Now?  He's the toast of the town.
