 Myrna Loy (qv) was originally offered the part of Dora Charleston  (a role that was a spoof of the character that she had played in the  Thin Man movies) but she wisely declined, later stating that "it  would have been ridiculous to have Myrna Loy doing Myrna Loy". She  also stated that she didnt want her "ass pinched by  David Niven (I) (qv)".
