Film, according to mother, carried by star (8)
I believe the answer is:
superman
'star' is the definition.
(thesaurus)
'film according to mother carried' is the wordplay.
'film' becomes 'sun' (I can't explain this - if you can you should give a lot more credence to this answer).
'according to' becomes 'per' (I've seen this before).
'mother' becomes 'ma' (ma can mean mother).
'carried' is an insertion indicator (one word carried by another word).
'per'+'ma'='perma'
'sun' going around 'perma' is 'SUPERMAN'.
'by' is the link.
Can you help me to learn more?
(Other definitions for superman that I've seen before include "Comic book hero" , "Kent some time" , "reporter's alter ego" , "Heroic figure" , "great guy" .)
