From the casting call for episodes 21/22:

[BERKOV] Russian Aide to the Russian Delegate working at the UN in NY. Mid 30s to mid 40s. Must be able to do a slight Russian accent.. Should be more upscale. In Episode 22…NICE CO STAR ROLE

Three days after this casting call was posted, Davoli excitedly tweeted “I BOOKED 24!!!” and on March 22 he posted a message to his Facebook fan group saying “Great time shooting 24 today. Stay tuned for episode #22.”

Canadian pop star and teen sensation Justin Bieber has joined the cast of 24, playing an ambitious young CTU Field Agent who will partner with Jack Bauer (Kiefer Sutherland) in the final two episodes.

“Justin is nothing short of a phenomenon,” says “24″ executive producer and showrunner, Howard Gordon. “It’s so rare to find an artist this young with such pure star quality and dynamic presence. This is an exciting time for Justin Bieber fans, for the 24 family, and for television in general.”

“Bieber Fever has taken over with 150 million views on YouTube and total domination of Twitter trending topics for months. This series finale will be the most talked about television event of the decade thanks to Bieber’s star power,’” Fox TV spokesman Chris Alexander added.

24 has traditionally cast Canadian actors including Elisha Cuthbert, Leslie Hope, Carlo Rota, and Colm Feore as First Gentleman Henry Taylor. The series star, Kiefer Sutherland, and it’s directors Brad Turner and Milan Cheylov are also Canadian.

Bieber’s newest album “My World 2.0″ sold over 283,000 copies in the past week according to figures provided by Nielsen SoundScan, earning him the number one spot on Billboard 200.

Production on the “24″ series wraps next week after eight years. At the conclusion of Season 8, 24 will have a produced a total of 194 episodes (including “24: Redemption”), making it one of the longest-running action television shows in history.

DISCLAIMER: THIS WAS AN APRIL FOOLS DAY JOKE. IT’S NOT REAL. Thanks to all of those who played along and retweeted etc (and sorry for those that got fooled – be glad it’s not real!). And for the guy who emailed me, yes I do feel a little dirty for having researched Bieber.

Assaf Cohen will be playing a villain in the double-hour episode (15/16) next week (April 5th).

On March 22, 2010, Assaf will Guest Star as a murder suspect on CSI: MIAMI. Two weeks later, on April 5th, Assaf returns to FOX’s “24″ as a bad guy!

He previously played the terrorist “Yassir” who worked under Habib Marwan in 24 Season 4.

Actress Sarah Hollis will be portraying Susan, a Presidential Aide in eight episodes of 24 Season 8. Her first appearance is in episode 14 on Monday March 29th.

Also making her first appearance in episode 14 is Christina Cox who plays Secret Service Agent Molly O’Connor.

24 is bringing in a TV veteran to help save Jack’s latest (and possibly last) bad day: Eriq La Salle has signed on to appear in this season’s final two episodes, sources confirm to me exclusively.

Fox has yet to officially announce whether 24 will end its eight-season run this May but clues continue to pop up that suggest otherwise. Here’s the latest: a casting call for the role of a U.N. secretary general on 24 went out to talent agencies this week and included an advisory: “These are the final episodes, so if some of your name people would like to do something on the show, this is the time for them to do it.”

This can be taken one of two ways – the final episodes of the season, or the final episodes of the series. It doesn’t sound too promising though: when read in context, the casting call is basically telling actors ‘now is your last chance to be on 24‘.

When you need a bad-ass, who better to call than Michael Madsen, who has played that role so well in such films as Reservoir Dogs, Thelma & Louise, Kill Bill and Free Willy 2: The Adventure Home (er…scratch that last one)? Now, the much sought-after 52-year-old has been cast on Fox’s 24 as Jim Ricker, a character sources describe to me as an ex-military guy from Jack Bauer’s past. Meaning, of course, a bad-ass.

Ricker will pop up as the clock ticks toward the final hours of Day Eight, which is looking more and more like Jack’s last day on TV before he heads to the movies.

Although it wasn’t mentioned in the article, I know Madsen has been filming 24 since February. There’s a recent photo of him on the set here. Could Ricker’s ex-military roots tie into the Operation Nightfall mission perhaps? Whatever the case may be, Michael Madsen should be a pretty cool addition to 24 – Madsen has played some great villains in the past.

Patti Stanger, host of Bravo’s television show Millionaire Matchmaker and author of Become Your Own Matchmaker has filmed a scene for 24 today.

Update: Scott tells us in the comments that it was a co-star role and not a guest star. He has also revealed on his Twitter page that he is playing a businessman and has already finished shooting his part.

Nazanin Boniadi (General Hospital’s Leyla Mir) has been cast on 24 as simply “blonde woman” – she can be seen in the set photos from yesterday wearing a (terrible looking) blonde wig.

It appears as if Michael Gaston (Jericho‘s Gray Anderson) is playing a character named General David Brucker who first appears in the fourteenth episode (5:00 a.m.-6:00 a.m.).

Actor and stuntman Chris Gann is playing a character named Mathis in the 14th episode. He actually played two characters on 24 before (in addition to doing stunt work for the show), both in the same season. First he was a CTU sniper, then he played Phillip Bauer’s henchman in the season 6 finale. No word on if his season 8 character is good or bad.

Jamison Haase seems to be playing a character named “Jim Payne” in the 16th episode (7:00 a.m.-8:00 a.m.).

Assaf Cohen has posted on his website that “he returns to 24 in 2010 as a bad guy” (Cohen had previously played a terrorist in the fourth season of 24).

Actor Larry Sullivan who played a Secret Service agent in season 7, updated his Twitter with the tweet “Fitting for 24 this afternoon…glad to be asked back…excited to work with the lovely and talented Cherry Jones again.”

You may have been watching the newly released 24 trailer and wondering which actor plays this frequently seen sniper:

That would be none other than Cliff Simon, best known for portraying Ba’al in Stargate SG-1. The official Cliff Simon fansite has his character listed as “Russian Sniper” with an appearance in the first episode of the season.

Akbar Kurtha plays Farhad Hasan. He can be spotted briefly in the leaked “Survive” promo – walking alongside his brother Omar Hassan (Anil Kapoor), Omar’s bodyguard Tarin Karoush, Jamot (played by Navid Negahban), and being led by Cole Ortiz (Freddie Prinze Jr). As a refresher, here’s the casting call for Farhad Hassan (then known as Farhad Hashemi):

Farhad Hashemi, Middle Eastern, 30s – 40s. Hashemi is the Secretary of State of a fictional Middle Eastern country, and his brother is the President. He does not completely trust the Americans, and he is reluctant to enter into a peace treaty with the United States.

Actress Christina Cox (who recently starred in ABC’s Defying Gravity and Showtime’s Dexter) has updated her official website with news of her joining the 24 cast.

24! Season 8…
OCTOBER 15TH, 2009
Christina is currently filming “5 am – 6am” on Fox’s Emmy Award winning 24. She’s playing Secret Service Agent ‘Molly O’Connor’.

Actor John T. Woods has updated his official web page with the text “Co-starring on ’24′ on FOX. Filming in Oct.”

According to his IMDB listing, Woods will be playing a character named “Bellow” in (at least) the 12th episode, which is 3AM to 4AM in the storyline. It’s not clear as to whether this will be a recurring character or if it’s just a single episode gig.
