Article by female is containing 50 minute pictures (7,5)
I believe the answer is:
feature films
'pictures' is the definition.
(feature film is a kind of picture)
'article by female is containing 50 minute' is the wordplay.
I cannot quite understand how this works, but
'article' could be 'a' (the indefinite article in English) and 'a' is located in the answer.
'female' could be 'ms' (Ms. is an example) and 'ms' is located in the answer.
'50' could be 'l' (Roman numeral) and 'l' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for feature films that I've seen before include "Pictures" , "Principal movies in cinema programmes" .)
