Gilles Marini, of 'Dancing With the Stars' and 'Sex and the City' movie fame, starts a five-episode arc Sun., Oct. 18 as French artist Luc Laurent, a love interest for Rachel Griffiths' Sarah.

'The Celebrity Apprentice'
(Sun., 9PM, NBC) 8th season premiere
It's certainly an eclectic group of celebs who've assembled for Donald Trump's latest season.

Headlining the list: Joan Rivers and her daughter Melissa; foul-mouthed comedian Andrew Dice Clay; other Kardashian sister Khloe; Tom Green; R&B crooner Brian McKnight; country star Clint Black; former NBA star Dennis Rodman; and reality TV star/Mr. Sandra Bullock Jesse James among them.

The celebs, who are playing to win a hunk of cash for their favorite charities, will face challenges like making and selling cupcakes and creating their own comic book superheroes, but with a contestant pool this diverse, we have a feeling it's going to be all about the ego clashes this season.

'Eastbound and Down'
(Sun., 10:30PM, HBO) series premiere
You probably know him from 'Pineapple Express' and 'Tropic Thunder' (or, for you indie film fans, 'The Foot Fist Way'), but wild and crazy character actor guy Danny McBride is headed to the small screen in this comedy from producers Will Ferrell and Adam McKay.

McBride is Major League Baseball pitcher Kenny Powers, whose loutish behavior on and off the field have led to his permanent ouster from the game.

And since he wasn't exactly a big saver he's dead broke his only option is to slink back to his North Carolina hometown, sponge off his brother and take a job as a gym teacher at his old junior high school.

'Living Proof'
(Sat., 9PM, Lifetime)
Harry Connick, Jr. steps away from his usual comedic and musical stylings for this fact-based movie, the uplifting and heartbreaking tale of cancer research doctor Dennis Slamon's journey to get the drug Herceptin approved for breast cancer treatment.

Oscar winner Renee Zellweger is a producer and Bernadette Peters, Regina King and Angie Harmon co-star in the story, which chronicles Slamon's battle against bureaucratic maneuvering and money issues before Herceptin was finally approved in 1998.

Connick and his female cohorts are terrific in the Breast Cancer Awareness Month flick, making a box of Kleenex a necessity for watching the drama unfold.

President Palmer ... Mayor Quimby ... President Roslin ... see where they rank on our list.

Just like their real-life counterparts, TV politicians will say and do anything to get your support.

The difference? Instead of a ballot, they want you to vote with your remote. And on TV, a politico's constituents are nothing more than ratings boosters. OK, so maybe there's not a huge difference.

From the obvious (three 'West Wing' pols make the list) to the more obscure (did you even know there was an elected official on 'The Wire'?), we count down the top 20 TV politicians of all time. Read through our list and let us know if you think we need a recount or if our list is full of winners.

'Desperate Housewives'
(Sun., 9PM, ABC) 5th season premiere
The women of Wisteria Lane have leapt five years into the future, and what a difference a day -- or five years' worth -- makes.

Susan and Mike: kaput, and Susan is now hooked up with that hot season four finale guy who looked a lot like 'Queer as Folk's' Gale Harold. Because he is. Meanwhile, Lynette's twin 'tween terrors have become twin teen terrors, Bree's lost custody of her grandson and Gaby's lost control of her kids and her model figure.

And then there's Edie, who makes a surprising return to the 'hood, with a surprising partner in tow: Dave, her new hubby, who's bringing the latest 'DH' mystery with him.

"What isn't happening with Justin?"

The Walkers are back (third season premieres Sunday, Sept. 28 at 10 PM EST on ABC), and they've got more illegitimate kids, new love connections and plenty of wine to wash it all down.

'Brothers & Sisters' star Dave Annable plays Justin, the war vet with an on-again, off-again drug habit and an eye for his onetime possible half-sister, who became just a hot chick he likes after a climactic DNA test.

Annable talked to AOL TV about Brad Pitt joining the cast (OK, maybe he was kidding), the mysterious new Walker sibling, staying out of the tabloids (unlike some of his costars) and paying the paparazzi to follow him to Subway.
