I hope you mean Jeff Bridges.^Indeed, especially since he was already waning with The Dark Knight.
Frankly I don't have a clue at who could play Old Bruce.
Although Beau Bridges may work.
The Big LeBatski. Co-starring John Goodman as Gordon ('Jim, I love you, but you've got to face the fact that you're a goddamn moron!).
Actually, Jeff was one of the names rumoured to be playing the role in the late 1980s.
When I heard John Goodman, I spontaneously thought of the Penguin.
