Michael Caine, who played Alfred in Batman Begins and the follow-up The Dark Knight, said that he doesn’t expect to see a sequel to the Christopher Nolan-helmed franchise for at least three years:
“All I know is that Christopher Nolan, who writes and directs Batman is doing a picture called Inception, and I’m not in it. So I think another Batman film is a long long way off. Long Way. I would say three years, must be.”
The film mentioned, Inception, hits theaters on July 16, 2010. There was a three-year gap between Batman Begins and The Dark Knight, so a 2012 release would be a bit longer than average (wider than the gap between the first four Batman films as well — 1989, 1992, 1995 and 1997).
