Christopher Cantwell is a writer, producer and director whose work in television and film includes co-creating the long-running drama series Halt and Catch Fire. He made an instant impression at Marvel Comics with his run on Doctor Doom, which took readers behind the mask of one of fiction's greatest villains. Moving from one armored protagonist to another, Cantwell helmed a relaunch of Iron Man, bringing a classic flavor to the Golden Avenger's adventures. In United States of Captain America, Cantwell reunited those who have wielded the shield and introduced a number of diverse new Sentinels of Liberty across the nation.
