Leading man to fight in Bosnian town (5,4)
I believe the answer is:
'leading man' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'fight in bosnian town' is the wordplay.
'fight' becomes 'vie' (I've seen this in other clues).
'in' is an insertion indicator.
'bosnian town' becomes 'mostar' (I can't explain this - if you can you should believe this answer much more).
'vie' inserted within 'mostar' is 'MOVIE-STAR'.
'to' is the link.
Can you help me to learn more?
(Other definitions for movie star that I've seen before include "VIP on set" , "Big player" , "Film idol" , "Cruise, perhaps" , "Hoping for an Oscar" .)
