General Crack is a 1929 American pre-Code sound all-talking historical costume melodrama with Technicolor sequences which was directed by Alan Crosland and produced and distributed by Warner Bros. It was filmed and premiered in 1929, and released early in 1930. It stars John Barrymore in his first full-length talking feature. The film would prove to be Crosland and Barrymore's last historical epic together. It was based on the 1928 novel General Crack by the British writer Marjorie Bowen, published under the name George Preedy, one of her several pen names.
