Honestly, if you ask any die-hard fan of the show about Day 6, you’re gonna get a mixed reaction. It’s complicated. By the time 2007 rolled around, 24 was a juggernaut, coming off the massive high of Season 5, which basically swept the Emmys. People expected the world. What they got was a 24 series 6 cast that felt a bit like a transition period—some legends returned, sure, but we also got a weird influx of Jack Bauer’s family members that nobody really asked for. It was a bold swing. Some of it landed, and some of it... well, it just didn't.
Jack was back, obviously. Kiefer Sutherland returned after being kidnapped by the Chinese at the end of the previous year, looking absolutely haggard and broken. That opening episode? Brutal. But the surrounding players in the 24 series 6 cast were the ones who had to carry the heavy lifting while Jack was dealing with his trauma.
The Heavy Hitters and the Return of the Fan Favorites
Mary Lynn Rajskub as Chloe O'Brian is basically the glue of the entire series, and she’s arguably at her peak here. Her dynamic with Morris O'Brian (played by Carlo Rota) gave the CTU scenes some much-needed humanity. Morris was actually a brilliant addition. He brought this snarky, vulnerable British energy that countered the "world is ending" vibe.
Then you have James Morrison as Bill Buchanan. He's the stoic leader we all wanted to work for. In Season 6, his role becomes even more poignant as he tries to navigate the political minefield laid by the White House. Speaking of the White House, we saw DB Woodside return as Wayne Palmer. It was a tough sell for some. Following in the footsteps of Dennis Haysbert’s David Palmer is an impossible task, but Woodside played Wayne with a specific kind of desperation that felt authentic to a man trying to live up to a ghost.
- Kiefer Sutherland (Jack Bauer): The heart of the show.
- Mary Lynn Rajskub (Chloe O'Brian): Tech genius and Jack's only real friend.
- DB Woodside (Wayne Palmer): The President struggling with a legacy.
- James Morrison (Bill Buchanan): The moral compass of CTU.
- Jayne Atkinson (Karen Hayes): The political operative with a conscience.
Peter MacNicol joined the 24 series 6 cast as Tom Lennox, the White House Chief of Staff. He was fantastic. If you remember him from Ally McBeal, this was a total 180. He was twitchy, manipulative, and yet somehow you ended up rooting for him by the end of the day. His verbal sparring matches with Powers Boothe—who played Vice President Noah Daniels—are easily the highlights of the middle-to-late hours of the season. Powers Boothe just had that voice, didn't he? He sounded like gravel and authority.

The Bauer Family Drama: A Controversial Choice
This is where things get polarizing. The creators decided to expand the "Bauer-verse." We met Jack’s father, Phillip Bauer (played by James Cromwell), and his brother, Graem (Paul McCrane).
Look, James Cromwell is an acting legend. There’s no debating that. But turning Jack's dad into a cold-blooded mastermind responsible for some of the season's nuclear threats felt a bit "soap opera" for some fans. It shifted the scale from global geopolitical stakes to a weirdly intense family feud. Paul McCrane, who most people remember as the guy who got hit by the van in RoboCop or the doctor who lost his arm in ER, played Graem with a slithery, corporate evil that made him very easy to hate.
The addition of Rena Sofer as Marilyn Bauer and Evan Ellingson as Josh Bauer (Jack's nephew) added to this domestic drama. It was a lot of screentime dedicated to Jack’s past. Some critics at the time, including those at Entertainment Weekly, felt this distracted from the core tension of the suitcase nukes. It’s a valid point. When the world is about to end, do we really care about Jack’s sister-in-law’s old feelings for him? Probably not as much as the writers thought we would.
New Faces at CTU and Beyond
We can't talk about the 24 series 6 cast without mentioning the new CTU staff. Rick Schroder came on as Mike Doyle. He was the "tough guy" foil to Jack. He was aggressive, played by the rules until he didn't, and had a scar that screamed "backstory." Schroder actually did a great job of being the guy you wanted to punch but also wanted on your side in a gunfight.

Marisol Nichols played Nadia Yassir. She was a breath of fresh air—a competent, high-level staffer who had to deal with some pretty ugly profiling within the office. It was a timely storyline. Then there was Eric Balfour as Milo Pressman, returning after a long absence since Season 1. Seeing him back was a nice nod to the show's roots, even if his character’s arc ended in a way that felt a bit abrupt for most viewers.
On the villain side, we had Adoni Maropis as Abu Fayed. He was a terrifyingly effective antagonist for the first half of the season. He felt like a real threat. But then the season shifted focus to the Chinese government and Phillip Bauer, and Fayed sort of lost his momentum. That’s the thing with 24; the villains have to be as interesting as Jack, or the whole thing sags.
Why Season 6 Felt Different
There was a lot of pressure. Season 5 had just won the Emmy for Best Drama Series. The expectations were astronomical. The 24 series 6 cast had to deal with a script that was, quite frankly, repeating some old beats. We had another nuclear threat. Another mole in CTU (kinda). Another President in a coma.
But the acting stayed top-tier. Even when the plot got a little "out there," the cast sold it. Regina King joined the cast as Sandra Palmer, Wayne’s sister. She brought a massive amount of gravitas to a subplot involving civil liberties that, while slightly disconnected from Jack's mission, added a layer of intellectual depth to the season. You can’t go wrong with Regina King.

The Legacy of the 24 Series 6 Cast
In hindsight, this cast represents the end of an era. It was the last season before the 2007-2008 writers' strike, which famously delayed Season 7 and led to the Redemption TV movie.
When you look back at the 24 series 6 cast, you see a bridge between the "Classic 24" (Seasons 1-5) and the "Global 24" that came later. It was the year we realized Jack Bauer couldn't just be a hero; he had to be a tragic figure whose very existence destroyed the people he loved. The cast carried that weight. Even the characters people hated, like Phillip Bauer, served to show that Jack came from somewhere dark.
Key Takeaways for Fans and Researchers
- Diversity of Talent: The season featured a mix of veteran character actors (Powers Boothe, James Cromwell) and rising stars (Marisol Nichols, Regina King).
- Character Returns: This season leaned heavily on nostalgia, bringing back Milo Pressman and several villains from Jack’s past in the later hours.
- Shift in Stakes: The 24 series 6 cast was tasked with making a personal family story feel as big as a national security crisis.
- Political Commentary: Through characters like Tom Lennox and Sandra Palmer, the season explored the tension between security and liberty more than previous years.
If you’re revisiting the series, pay attention to the smaller performances. Harry Lennix as Walid Al-Rezani provided a heart-wrenching look at the cost of being an informant. These guest spots are what actually made the world of 24 feel lived-in and dangerous.
To get the most out of a rewatch or a study of this specific season, focus on the transition of power in the White House scenes. The chemistry between MacNicol and Boothe is a masterclass in political drama that often gets overlooked because people are waiting for Jack to jump out of a plane. Watch the nuance in their arguments. It’s where the real "prestige TV" writing was hiding that year.
Moving forward, the best way to analyze the impact of this cast is to compare the "CTU Dynamic" here to the more streamlined versions in the later London-based Live Another Day. You’ll notice that Season 6 was perhaps the last time the show tried to maintain a massive, multi-location ensemble before narrowing its focus. Check out the behind-the-scenes features on the DVD sets if you can find them; the interviews with Rick Schroder about joining such an established team provide some great context on the set's intensity.
