"Citizen" played by Orson Welles (4)
I believe the answer is:
'citizen played by orson welles' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for kane that I've seen before include "Great Orson Welles movie 'Citizen . . . .'" , "'Citizen . . . .', great film by Orson Welles" , "Famous film by Orson Welles 'Citizen . . . .'" , "Orson Welles's film ` `Citizen ....' '" , "1941 cinematic citizen" .)
