She features in novel, say? Yes and film (4)
I believe the answer is:
elsa
'she' is the definition.
'features in novel say? yes and film' is the wordplay.
'ELSA' is hidden within the letters.
But, I'm unsure how the hidden word is indicated.
(Other definitions for elsa that I've seen before include "Girl" , "Lioness (born free in Kenya)" , "Famous lioness" , "Big cat" , "___ Schiaparelli, Italian-born French fashion designer d. 1973" .)
