Television viewers know Kiefer Sutherland as the no-holds-barred U.S. counter-terrorist agent Jack Bauer. However, the life of this colorful Canadian actor has also been filled with action, danger, and trouble. Author Christopher Heard unearths Kiefer’s dramatic story in his new biography. Once engaged to Julia Roberts, Sutherland’s movie career started to slide in the 1990s. At one point, he even left Hollywood entirely. He bought a ranch in Montana and was victorious on the rodeo circuit.
