The X-MEN star, 67, announced he was homosexual to the world during a BBC radio interview in 1988, but he still feels guilty for not revealing his sexual orientation to his beloved mother Margery, and father Denis.
He says, "I have a few regrets in my life but that is number one. My mother died when I was 12 and my father when I was 24. I knew by then of course.
"I was just getting round to it, thinking this was a conversation I had to have with my father. (Then) he died and I never told him."
