My favorite DeMille movie has gotta be the incredible Sign of the Cross (1932), followed by the surprisingly subtle and moving The Cheat (1915). If you would like a taste of DeMille, you might enjoy Samson and Delilah (1949) which is being broadcast by TCM tonight at midnight ET on Sept. 24th. Maybe this time that lion will win his wrestling match with Victor Mature?
