What is the theme in Rocket to the Moon by Clifford Odets?

Another theme is marriage and career. While Stark agrees to Belle's demands at the very beginning of the play, the ramifications of this decision are felt throughout it. Although Stark capitulates to Belle's wishes, he feels confined and stifled by his present position. As a way to escape this feeling, Stark carries out a brief affair with his secretary, Cleo. Stark's attempt to deal with his professional disappointments through an extramarital affair highlights one of the central themes of the play—the effects of marriage on a man's career aspirations.
