Cavett was present when actor Marlon Brando broke the jaw of paparazzo photographer Ron Galella on June 12, 1973.
In December 2012, for their annual birthday celebration to "The Master," The Noel Coward Society invited Cavett as the guest celebrity to lay flowers in front of Coward's statue at New York's Gershwin Theatre, commemorating the 113th birthday of Sir Noel.
