Amazon’s new original series Alpha House has just added a handful of notable names to its cast. The company announced that Cynthia Nixon (Sex and the City), Amy Sedaris (Strangers with Candy), comedian Wanda Sykes, and Julie White will join the show, which is set to premiere this fall.

The show was one of five original series greenlit by Amazon back in May, following a trial period that featured 14 pilots from Amazon Studios. Viewer feedback played a key role in which shows got the go-ahead, and the others to make the cut included Betas, Annebots, Creative Galaxy, and Tumbleaf. Alpha House stars John Goodman and was written by Doonesbury‘s Garry Trudeau. It centers on four U.S. Senators who live together in a rented house in Washington D.C. The pilot episode is available to watch, for free, on Amazon Instant Video.

From Amazon:

Alpha House follows four Republican senators-turned-housemates, Gil John Biggs (John Goodman), Robert Bettencourt (Clark Johnson), Louis Laffer (Matt Malloy) and, Andy Guzman (Mark Consuelos) through re-election battles, looming indictments, parties and housemate drama. Nixon will play Senator Carly Armiston, the formidable, confident, Democratic senator from New York . She is joined by Sedaris, who will play Louise Laffer, the sweet, concerned wife of Senator Louis Laffer. Sykes will play Senator Rosalyn DuPeche, a strong-willed, funny Democrat who just happens to be a neighbor of the male senators, while White will play the tough, determined, yet charming southern wife to Goodman’s character Gil John Biggs.

“We’re lucky enough to have four of the most talented performers around joining the show,” said Trudeau.

With its original programming, Amazon seems to be bucking the trend that Netflix has set – debuting all of the episodes in one big chunk.

“It hasn’t been entirely determined how they’ll put it out. But it will be a different model than the one used by Netflix,” says the show’s producer, Jonathan Alter.
