Actor redoing short plays (2,4)
I believe the answer is:
de niro
'actor' is the definition.
(I know that De Niro is a actor)
'redoing short plays' is the wordplay.
'short' means to remove the last letter.
'plays' indicates an anagram.
'redoing' with its final letter taken off is 'redoin'.
'redoin' is an anagram of 'DE NIRO'.
(Other definitions for de niro that I've seen before include "Robert ... (''you talkin' to me?'')" , "Actor who plays mainly tough characters" , "Robert . . . . . ., film star of ''Taxi Driver'' and ''Raging Bull''" , "Robert ..., film actor" , "Robert . . . . . ., male movie star of 'Taxi Driver' and 'Raging Bull'" .)
