While there was a 1957 television adaptation of "The Twelve Pound Look", there is no widely known record of the cast for that specific adaptation. There are several film and television adaptations of the play throughout the 20th century, but finding information on the 1957 adaptation is difficult.
However, I can tell you some actors and actresses who have starred in different versions of "The Twelve Pound Look" throughout history:
* Margaret Rutherford starred in a 1937 film version.
* Gertrude Lawrence starred in a 1932 film version.
* Wendy Hiller starred in a 1934 film version.
If you can provide more information about the 1957 adaptation, such as the broadcaster or any other details, it might be possible to find the cast list.
