"Raging Bull” star (2,4)
I believe the answer is:
de niro
'raging bull star' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for de niro that I've seen before include "American actor, b. 1943" , "Starred in The Godfather and Raging Bull" , "Actor who plays mainly tough characters" , "Robert . . . . . ., male movie star of 'Taxi Driver' and 'Raging Bull'" , "Robert ..., film actor" .)
