Actress Kendrick (4)
I believe the answer is:
'actress kendrick' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for anna that I've seen before include "worth very little in India" , "copper, once, in India" , "The name's the same,either way" , "-- Karenina, Tolstoy novel" , "Book by Tolstoy" .)
