Identical trees moved into filming area for TV programme (6,6)
I believe the answer is:
sesame street
'tv programme' is the definition.
(children's TV programme)
'identical trees moved into filming area' is the wordplay.
'identical' becomes 'same' (similar in meaning).
'moved' indicates an anagram.
'into' is an insertion indicator.
'filming area' becomes 'set' (eg a film set).
'trees' anagrammed gives 'stree'.
'same'+'stree'='samestree'
'samestree' going within 'set' is 'SESAME STREET'.
'for' acts as a link.
(Other definitions for sesame street that I've seen before include "TV program" , "where Elmo lives" .)
