Was it Frank Rich or David Richards who talked about the vocal demands blocking the casting of ideal candidates like MacLaine? I recall reading that take, how the Norma arias demand the big soaring voices. The Close model -- actor with decent but not stellar singing -- wasn't duplicated as often as people expected. Even Clark still brought a powerful pop instrument in the part. I also read the Cybil Shepard wanted the role desperately. As funny as that sounds, she can sing, and it's not hard to picture her pulling it off. Sally Field, however, mentioned here, makes me giggle.
