Caine or Law title role (5)
I believe the answer is:
alfie
'caine or law title role' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for alfie that I've seen before include "well-known film" , "Michael Caine role reprised by Jude Law" , "Name of fellow" , "Early Michael Caine film" , "1966 Michael Caine film" .)
