Sailor bitter about boarding ship produces film (4,4)
I believe the answer is:
star wars
'film' is the definition.
(I've seen this before)
'sailor bitter about boarding ship' is the wordplay.
I cannot really understand how this works, but
'sailor' could be 'tar' (tar can mean a sailor) and 'tar' is located in the answer.
'about' could be 'a' (abbreviation in Chambers) and 'a' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'produces' is the link.
Can you help me to learn more?
(Other definitions for star wars that I've seen before include "George Lucas's cult sci-fi film" , "Picture" , "Strategic Defense Initiative (US) - sci-fi film" , "Space fiction film - SDI" , "SF film" .)
