Bow on the screen (5)
I believe the answer is:
clara
'bow on the screen' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for clara that I've seen before include "Woman" , "- - Bow, silent film star" , "Home town of the Taoiseach" , "Butt" , "-- Bow, silent film actress" .)
