Kiefer Sutherland open to more 24

There was the original 24 with Kiefer Sutherland as Jack Bauer, that lasted for 6 or 7 seasons. Then a few years later there was one new season, taking place in London, also with the same actor and character. Some time later there was a new 24 following the same format but with completely different characters. I don't know if the plan was for it to run for several years, but it only lasted one season.
