North by Northwest star (4,5)
I believe the answer is:
cary grant
'north by northwest star' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cary grant that I've seen before include "US film actor born in England" , "Hollywood star of film of "Arsenic and Old Lace"" , "Hollywood great, born in Bristol" .)
