sentences:  In 1963, Morey Amsterdam and Pat Carroll each filed $12,000 suits against Hanna-Barbera for breach of contract, claiming they had been cast and signed to the roles of George Jetson and Jane Jetson, respectively.Although their contracts stipulated they would be paid US$500 an episode with a guarantee of twenty-four episodes (i.e., a full season) of work, they recorded only one episode before being replaced.Several sources claimed the change had occurred as a result of sponsor conflict between Amsterdam's commitment to "The Dick Van Dyke Show" and Carroll's to "Make Room for Daddy".
