Fox will follow up its "X-Files" event series with two more reboots of popular shows from the network's past - "24" and "Prison Break."

Fox has ordered a "24" spinoff pilot, titled "24: Legacy," that will feature all-new characters, but retain the show's format of real-time storytelling, split screens and episodes that cover one hour per episode. The new series will not feature Kiefer Sutherland in his iconic role of Jack Bauer, but former executive producers Howard Gordon, Manny Coto and Evan Katz will all return.

"24: Legacy" will follows a military hero who returns to the U.S., but trouble follows him home. He's compelled to ask CTU for help in saving his life and stopping a potentially one of the largest-scale terror attacks on American soil.

To replace Jack Bauer, the show will cast a non-white actor, which Fox CEO Dana Walden confirmed to reporters on Friday.

"The character was originally conceived as being a diverse actor," Walden said. "We wanted it to be as different from Jack Bauer as possible. That was the original thinking behind having this be a diverse lead. Whether that's African-American or a Latino actor, we've been really excited by some of the people we've been seeing throughout our internal process."

The pilot will film this winter.

Fox will also reboot "Prison Break" as an event series in the same vein as "The X-Files" revival. Wentworth Miller and Dominic Purcell will both return to reprise their roles as brothers Michael Scofield and Lincoln Burrows.

The limited series will address Michael's death from brain cancer that occurred in the straight-to-video "Prison Break" movie while also providing "a logical and believable explanation to why the characters are alive and still moving around the world," Walden told reporters in August, according to Deadline.

The story will unravel on "an international landscape. It's not a domestic show," Walden said at the Television Critics Association winter press tour. She also expressed confidence that other cast members from the original series will return.

"Prison Break" ran for four seasons between 2005 and 2009.
