BEVERLY HILLS — In an unusual casting move — OK, let’s say “unprecedented casting move” until proven otherwise . . . Amy Schumer will play three different animated characters on three different animated Fox series on . . . one night.

And that night is Sept. 25.

Fox TV chief Dana Walden announced Schumer’s latest project here at the TV Critic’s Tour on Monday.

There were no further details about the characters, but the shows are “The Simpsons, “Bob’s Burgers,” and “Family Guy” and, Walden said, Schumer has already taped her parts. The Rockville Centre-raised Schumer is not quite a voice-over novice — she voiced a character on one episode of Netflix’s “Bojack Horseman” last year.

In other Fox news, Mariah Carey will briefly join “Empire” in a guest role this fall. Per Fox’s news release, Carey “will play Kitty, a mega-superstar who comes to Empire to collaborate with Jamal Lyon (Jussie Smollett) on an explosive new song. When the duet encounters obstacles, Kitty helps Jamal dig deep to overcome personal difficulties and reach a musical breakthrough.” The episode airs Oct. 5.

Meanwhile, “The Simpsons” made a little news here, too. Showrunner Al Jean said a first-ever one-hour “Simpsons” will air in January. This hour will feature “Empire’s” Taraji P. Henson and Keegan-Michael Key (of “Key & Peele”) in guest voice roles.

Meanwhile, the 600th episode — that’s right, six hundred — will air Oct. 16. Here’s the through-line of an episode that will be this year’s “Treehouse of Horror:” “Mr. Burns introduces a ‘Hunger Games’-style contest in which Springfield’s children must fight each other; and Lisa’s imaginary best friend becomes jealous of Lisa’s real best friends.”
