Rich butter mom ordered for old movie star (6,7)
I believe the answer is:
robert mitchum
'old movie star' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'rich butter mom ordered' is the wordplay.
'ordered' indicates anagramming the letters.
'rich'+'butter'+'mom'='richbuttermom'
'richbuttermom' is an anagram of 'ROBERT MITCHUM'.
'for' is the link.
Can you help me to learn more?
(Other definitions for robert mitchum that I've seen before include "US actor in "Farewell My Lovely"" , "American star of "Night of The Hunter"" .)
