One is LC's film hero, the other a writing hero. What happened when they met to discuss Keaton starring in a film by Beckett that only had one spoken line ("Shhh")?:

Beckett arrived at Keaton's hotel, to find him watching a baseball game and drinking beer. Cronin takes up the story: 'Beckett, finding himself in the unusual position of having to make the running, ventured a few general words about his admiration for Keaton's work. When these petered out, everybody sat in silence while Keaton, seemingly unperturbed - though because of his famous mask, nobody could be sure - continued to drink his beer and watch the game. Every now and then Beckett, almost like somebody meeting Samuel Beckett for the first time, would venture a few words, to which Keaton would respond at best in monosyllables.' In a sentence that could easily pass for a stage direction from a Beckett play, Cronin concludes: 'The minutes passed, the situation seemed to get more harrowing and hopeless and the silences to become more interminable.'

He did make the film called "Film" and it was openly booed. My admiration has jumped ten-fold, fellows. (via The Guardian)
