Some cats will be more equal than others.

The Jellicle guru is Old Deuteronomy, a traditionally male role essayed here by Dench. In the stage show, Munkustrap (Robbie Fairchild) was a useful master of ceremonies for the proceedings, but Lloyd Webber has said that the movie will be seen through the eyes of Victoria, the White Cat (Francesca Hayward). That represents something of a promotion for this character, who will also be getting her own brand-new Oscar-bait Lloyd Webber song, with lyrics by one T. Swift.

Also watch for:

— Rum Tum Tugger, usually an Elvis impersonator, due for a welcome hip-hop/R&B updating at the hands of Jason Derulo.

— Macavity, the Napoleon of Crime, who, onstage, plays a relatively minor role in his own number. Odds are that onscreen, the top-billed Idris Elba will get more action.

— Gus the Theater Cat, a Centrum Silver a ctor who drags on about his days on the Victorian stage. Let us hope Ian McKellen can pump some juice into him.

— Bustopher Jones, a tuxedoed, white-spatted dandy who will be channeling the pathologically crowd-pleasing spirit of James Corden.

Grizabella the Glamour Cat is the de facto protagonist because, well, she’s the only one something happens to. A former prosti-kitty, she once “haunted many a low resort” and is now a social pariah among the snotty Jellicles. Her destiny is to totter into the spotlight at evening’s climax and sing That Song. Which reminds me …

For the love of all that’s holy, it’s not called “Memories.”

I don’t care what your great-aunt Celia says, or the woman who cuts your hair or the man you’re married to. It’s “Memory.”

(We might pause to note what a strangely tenacious error this has become for such an oft-recorded tune. Nobody insists on saying “White Christmases” or “Several More Bite the Dust.”)
