HAL's voice 2001: Space Odyssey, Douglas shared many of the same features as Kubrick's iconic creation: precision, steel strength, enigma and infinite intelligence, as well as a bad sense of humor.

Douglas owned his talents at the stages of his hometown and we are proud of our dedication to the production of the coming season Othello his memory. We owe so much to him. "
