Billy Bob Thornton, Dennis Quaid, Johnny Depp, Hugh Grant, Richard Gere and Benicio Del Toro are the latest crop of thesps heading Inside the Actors Studio with host James Lipton. The "intimate" chats — in which performers dissect the craft known as acting — will tape between Jan. 28 and April 15; air dates are TBA. So, what's with the all-male lineup? Couldn't Lipton at least get Markie Post??? Responds a Bravo rep: "It just so happened that the first six actors who were available on the taping dates were men."
