Channing Tatum popped up on the set of his new film, Foxcatcher, in Pittsburgh, PA, today. He looked dapper in a suit jacket and tie to begin filming for his latest project, which also stars Steve Carell, Mark Ruffalo, and Sienna Miller. It has been a big month for Channing. He was recently crowned People's Sexiest Man Alive for 2012, taking over the honor from his predecessor, Bradley Cooper. Channing was also recognized by another big publication, reaffirming his status as one of — if not the ultimate — Hollywood's hottest stars. Channing graces the cover of GQ's December issue, out on newsstands today, as one of their men of the year.
