Peter Mayhew (May 19, 1944 â April 30, 2019) was a British-American actor, best known for playing Chewbacca in the Star Wars films. Mayhew was born on 19 May 1944 in Barnes, Surrey, where he was also raised. His height was a product not of gigantism â "I don't have the big head" â but of an overactive pituitary gland secondary to a genetic disease called Marfan Syndrome. The overactive pituitary gland was treated successfully in his mid-teens. His peak height was 7 feet 3 inches (2.21 m)
