She had told Kazan that she was bored with the roles she was playing because so many of them had been basically the same kind of empty-headed characterization. She wanted nothing ore than to challenge herself with more complex parts--and also wanted others to think of her as being more than a caricature....Anytime she had an opportunity to broaden her mind, she wanted to take advantage of it.
Today...major actors and actresses develop their own projects or, at the very least, cherry-pick their roles carefully to suit not only their tastes but also whatever image they have cultivated to present to their public. Most major stars have their own production companies through which such projects are developed and even financed. While the biggest male stars of that time did in fact have their own production companies--Jimmy Stewart, Kirk Douglas, John Wayne, and Burt Lancaster, to name a few--and thus exerted creative and financial control over their careers, that was not the case with female stars. But Marilyn Monroe was about to change that.
