Concerning the naming of the servants John Carridine and as Barryman I heard probably from television so I do not have a good source that the renaming was to avoid what could have been a confusing reference to the Barrymore acting family It should be borne in mind that the then three famous members of the family John the Great Profile Lionel and Ethyl worked heavily although not exclusively for MGM studios I was not able to find any films by John or Lionel with 20 Century Fox
