He participated in USO tours to visit and perform for the troops for over a decade. "Robin was a gifted actor and comedian, but he was also a true friend and supporter of our troops," said Secretary of Defense Chuck Hagel in a statement.
Robin was voted least likely to succeed in high school. He sure showed them!
He was an avid cyclist (even noting it in his Twitter bio) and owned over 50 bicycles.
He ad-libbed most of his lines as the Genie in Aladdin. Apparently, Disney had 16 extra hours of material from him!
He named his daughter Zelda after the tiutular princess in The Legend of Zelda video game.
Robin and Christopher Reeve were lifelong friends after meeting at Julliard in the 1970s. Robin offered to pay any of Christopher's medical bills that he couldn't handle, and was on the Board of the Christopher Reeve Paralysis Foundation.
He was nominated for four Oscars, winning one for Good Will Hunting.
