London: Acting legend Clint Eastwood will return as the cop Dirty Harry.

Eastwood is 77 but will reprise the role as Inspector Harry Callahan who comes out of retirement to avenge his grandson's murder, thesun.co.uk reports. Eastwood first played the role in 1971 and last appeared as Callahan in 1988 in the movie "The Dead Pool".

An insider said: "He sees this as his final action film. He's looking forward to playing Harry again. But it'll be realistic - he'll be an old man."
