By all reports, no, she was never considered, but probably for good reason. Martin hadn't made a movie since the early 50s and was very open about not liking to work in film, preferring the stage and live TV. But another reason is that when Martin first appeared as Maria, she was already in her 40s. By the time the movie entered production, Martin was now over 50 and couldn't have convincingly played the young, virginal Maria on film.
