Stuart OK? Been upset for old movie comedian? (6,6)
I believe the answer is:
buster keaton
'old movie comedian?' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'stuart ok? been upset' is the wordplay.
'upset' indicates an anagram.
'stuart'+'ok'+'been'='stuartokbeen'
'stuartokbeen' with letters rearranged gives 'BUSTER KEATON'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for buster keaton that I've seen before include "Broken statue (anag) - early film star" , "Silent screen star" , "Silent film comedy star, d. 1966" , "silent clown - with 21d" , "old movie star" .)
