I did not watch the show or remember seeing him in any TV show or film but it is sad to me nonetheless.
From the LA Times:
The following is a statement from his wife, Vashti Whitfield: “On a beautiful sunny sydney spring morning, surrounded by his family, in the arms of his loving wife, our beautiful young warrior Andy Whitfield lost his 18 month battle with lymphoma cancer. He passed peacefully surrounded by love. Thank you to all his fans whose love and support have help carry him to this point. He will be remembered as the inspiring, courageous and gentle man, father and husband he was.”
