Val Kilmer tweets pictures of Mark Twain transformation Val Kilmer has given fans a peek into the make-up room, publishing photos of himself preparing to play American author Mark Twain. The star is playing the Adventures of Huckleberry Finn author for Citizen Twain at California's Pasadena Playhouse from 21-30 August. Kilmer, 53, wrote and directs the stage show, which he hopes to take to Broadway. And the Heat and Batman Forever actor undergoes quite a transformation for the role, which he tweeted pictures of. "Good Twain selfie," he captioned one of the shots. Last month, Kilmer told the Los Angeles Times: "There's a part of the makeup that starts to become the way I understand Mark Twain. He's old in my story ... old people are often frustrated because their movement becomes restricted.
