Four years after the clock ran out on 24, Jack Bauer is back! Kiefer Sutherland’s former CTU agent will return to Fox May 5 in 24: Live Another Day, a 12-episode limited series. At TCA winter press tour, the cast and producers talked about the show, which I wrote about for Quartz.

Yet despite Bauer’s significant backstory, “you can pick this series up without having seen season 8, or the show at all,” said executive producer Manny Coto. That said, it’s not just you: Not even the producers can keep track of all the show’s various twists and turns over the years. “Sometimes we have to check Wikipedia” to see if the characters are still alive, says Coto.

I also spoke with executive producer Howard Gordon about why the show, which has faked previous locations like New York City and Washington, felt it was essential to film on location in London.

This time, 24’s Jack Bauer only needs 12 hours to save the world
