Film feline (4)
I believe the answer is:
elsa
'film feline' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for elsa that I've seen before include "Famous lioness" , "Big cat" , "___ Schiaparelli, Italian-born French fashion designer d. 1973" , "Lioness (born free in Kenya)" , "Girl" .)
