Work in the direction of some films (4)
I believe the answer is:
toil
'work' is the definition.
(toiling is a kind of working)
'the direction of some films' is the wordplay.
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'direction of some films' becomes 'oil' (I am not sure about this - if you are sure you should believe this answer much more).
't'+'oil'='TOIL'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for toil that I've seen before include "Work incessantly" , "Manual labour" , "Work extremely hard" , "Drudgery" , "Work hard and long" .)
