The veteran actor even revealed his struggle with alcoholism was extremely difficult to overcome. "It took me a long time to get over it," he added. Dick is now sharing his story with the hope of inspiring others to overcome substance abuse issues. "I get a lot of letters from people, who say all of a sudden they weren't ashamed to admit they had a drinking problem and they got help," he shared. "So I'm very proud of that."
