Fox's "The Rocky Horror Picture Show" remake -- already set to become one of the great curiosities of the 2016 tv season -- has added Victoria Justice to the cast ...

And Reeve Carney ...

And Ryan McCarten ...

AND Staz Nair, who has some fame in the U.K. as a former "X Factor" contestant and has generated additional interest (or intrigue) since joining the new season of "Game of Thrones."

Carney, now on "Pennydreadful," is also of particular interest: He originated the role of Peter Parker in Julie Taymor's star-crossed "Spider-Man: Turn off the Dark." He'll play Riff-Raff here.

McCarten (starring on the Disney Channel's "Liv & Maddie") and Justice will play lovebirds Brad and Janet respectively.

Nair, meanwhile, will be Rocky Horror himself, the creation of Frank-n-Furter. Laverne Cox was cast in the lead role last October.

Let's see -- who's left? Magenta and Brad Majors. Fox promised additional casting announcements shortly.

 Justice -- I don't need to tell you -- was a teen star of considerable wattage -- "Zoey 101," "iCarly," and "Victorious." Her post-teen role in MTV's "Eye Candy" (the picture above) based on the R.L.Stine book of the same name did not last -- cancelled after a brief run last April.

 "Rocky Horror," meanwhile, arrives on Fox this fall. No launch date yet.  Lou Adler, Kenny Ortega and Gail Berman will produce (Gail: Former Fox chief...)
