As first Colbert guest, will George Clooney talk latest film or liberal politics?

Stephen Colbert gave a hint of what his “Late Show” gig will be like by announcing that George Clooney will be his guest when he takes over the Letterman legacy on Sept. 8.

Actor/director Clooney has a long history in show business, but also liberal causes and human rights issues, such as Darfur.

George Clooney will be my first-ever #LSSC guest on September 8th! Could one of you let him know?
