Make into a movie, say (5)
I believe the answer is:
adapt
'make into a movie say' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for adapt that I've seen before include "Become adjusted to new conditions" , "Change to suit new circumstances" , "Adjust (to new conditions)" , "Adjust (to changes)" , "Fashion" .)
