Type of film show cinema is fitting in initially? (3-2)
I believe the answer is:
sci-fi
'type of film' is the definition.
(science fiction film)
'show cinema is fitting in initially?' is the wordplay.
'initially?' suggests taking the first letters (I've seen 'initially' mean this).
The initial letters of 'show cinema is fitting in' is 'SCI-FI'.
(Other definitions for sci-fi that I've seen before include "Literary genre (abbrev)" , "Fantasy genre based in the future" , "Sort of book" , "Isaac Asimov genre" , "SF" .)
