Channing Tatum showed a lot of skin in his most recent movie, the military drama "Stop-Loss" and that was a good thing! Sadly, he's a lot more covered up in his next role as Duke in the upcoming movie version of "G.I. Joe." Oh well, I'd still pretty much watch anything he's in at this point. I finally checked out "Step Up" after interviewing Channing at the "Stop-Loss" premiere last month and am now a big fan,
