Film session gets so hot, oddly (5)
I believe the answer is:
shoot
'film session' is the definition.
(I've seen this in another clue)
'so hot oddly' is the wordplay.
'oddly' is an anagram indicator.
'so'+'hot'='sohot'
'sohot' anagrammed gives 'SHOOT'.
'gets' is the link.
(Other definitions for shoot that I've seen before include "Make a film" , "New growth; last word of Hamlet" , "away" , "Film; move rapidly" , "Say what you have to say" .)
