Billy Connolly says fellow comedian and actor Robin Williams was his ''hero''.
Connolly - a close friend of the 63-year-old actor and comedian, whose death is believed to be caused by suicide via asphyxiation - said that Williams had an unparalleled talent.
Reflecting on his relationship with the 'Good Will Hunting' star, Connolly said: ''Robin was both my friend and my hero, a unique talent and a kind and generous man; the world will be a much poorer place without him.
''Robin was one of the most uniquely brilliant and complicated comic artists the world has ever known. As a performer, he navigated a dangerous high wire at every single moment - with no safety net.''
Williams' 'Good Will Hunting' co-star Minnie Driver also paid tribute to the popular actor, saying: ''I never met anyone who loved making people laugh more than Robin.''
