Victoria Justice has joined Laverne Cox in Fox’s “Rocky Horror” remake, plus Louis C.K. is bringing a new animated series to FX, in today’s news roundup . . .

Casting News:

Fox’s “Rocky Horror Picture Show” event special is filling out its cast with the additions of Victoria Justice and Ryan McCartan, who will play sweethearts Janet and Brad, plus Reeve Carney, who will play Riff Raff and Staz Nair who will star in the title role.

Justice’s casting comes after the Nickelodeon alum inked a talent deal with Fox and 20th Century Fox last year. McCartan is known to young fans from starring on Disney Channel’s “Liv and Maddie,” Carney stars on “Penny Dreadful” and Nair is a newcomer.

“Rocky Horror” will shoot this winter. The two-hour event, based on the cult classic, is slated to debut in fall 2016 on Fox.

Lily Collins will star opposite Matt Bomer in Amazon’s “The Last Tycoon” pilot, which is based on the unfinished F. Scott Fitzgerald novel. Previously announced, Kelsey Grammer and Rosemarie DeWitt will also co-star in the 1930’s period piece, which hails from Sony TV’s TriStar Television.

Bomer will play Monroe Stahr, Hollywood’s first wunderkind studio executive who in the original book was inspired by film mogul Irving Thalberg. The pilot revolves around Stahr as he climbs the ranks and is pitted against his mentor and current head of the studio Pat Brady (played by Grammer), who is based off of Louis B. Mayer. DeWitt will play Brady’s wife, and Collins, whose casting was first reported by Deadline, will play Brady’s daughter Celia, a young rich girl in love with Monroe, who begins paying attention to her after her intriguing movie pitch.

“New Girl” is getting back an old friend — or, boyfriend? David Walton, who recurred throughout Season 2, playing Dr. Sam who dated Jess (Zooey Deschanel) will be back for the Fox comedy’s fifth season, TVLine reports. The TV pair broke things off after Jess and Nick (Jake Johnson) kissed. Though details on Walton’s return have not been released, the “About A Boy” alum will appear in a multi-episode arc, which is slated for March.

Development News:

Louis C.K. and Albert Brooks have teamed up on an animated pilot for FX. The duo will serve as co-creators, co-writers, exec producers and voice actors on the half-hour untitled comedy project, which hails from C.K.’s Pig Newton company. Details on the potential show’s premise are unclear, though C.K. and Brooks will voice the lead characters.

Cancellation News:

FXX has opted not to go forward with animated series “Cassius & Clay,” Variety has confirmed.

From Megan Ganz (“Modern Family,” “Community”) and “Archer” creator Adam Reed, the comedy’s voice cast was star-studded with the likes of Kaitlin Olson, Lake Bell, Susan Sarandon, Jeffrey Tambor, JB Smoove, Kevin Michael Richardson, Stephen Root, Katy Mixon and Robert Patrick. The once-series was described in the vein of “Butch Cassidy and the Sundance Kid.”

First put into development in May 2015, the comedy project was ordered to series this past August.
