All-embracing cinema clue solved (10)
I believe the answer is:
ecumenical
'all-embracing' is the definition.
(thesaurus)
'cinema clue solved' is the wordplay.
'solved' indicates an anagram (the anagram must be solved).
'cinema'+'clue'='cinemaclue'
'cinemaclue' anagrammed gives 'ECUMENICAL'.
(Other definitions for ecumenical that I've seen before include "of the church" , "seeking to promote unity" , "Promoting unity between churches" , "trying to promote unity" .)
