Everett Chambers, a television casting director on NBC’s Philco Playhouse and subsequently a good friend, said Cassavetes was the most persistent unemployed actor he ever saw. Cassavetes would come to his office; Chambers would, only half-facetiously, yell at him to get out and throw a telephone book at him; and Cassavetes would return the next week without fail. At one point, Cassavetes chained himself to a radiator at CBS to force them to give him a walk-on in You Are There. Underneath the nutty behavior, it was an extremely discouraging time. Cassavetes later said he could never afterward bear to ride the New York subway because it reminded him of these days of round-making. The problem Cassavetes and his friends were up against was that Actors Studio graduates were the only ones taken seriously by the early television producers.
