"Ben-Hur” star (6)
I believe the answer is:
heston
'ben-hur star' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for heston that I've seen before include "Service Area on M4" , "__ Blumenthal, celebrity chef" , "US star" , "Charlton __, actor - __ Blumenthal, chef" .)
