Shortly after Malloy had spoken about using some footage of Orson Wells‘ 1941 film ‘Citizen Kane’ in his documentary, White took his microphone and bullishly stated: “I’m gonna let you finish, I’m gonna let you finish, but Orson Welles did one of the greatest films of all time!”
The move garnered cheers and whoops from the audience, while Malloy also appeared to see the funny side of the joke.
