"Dear All," he said in a message issued by his representatives to People.com.
"It is time for me to chuck in the sponge. To retire from films and stage. The heart for it has gone out of me: it won't come back," he said.
"My professional acting life, stage and screen, has brought me public support, emotional fulfillment and material comfort. It has brought me together with fine people, good companions with whom I've shared the inevitable lot of all actors: flops and hits. However, it's my belief that one should decide for oneself when it is time to end one's stay. So I bid the profession a dry-eyed and profoundly grateful farewell. Ever, Peter O'Toole."
