DreamWorks Animation president Jeffrey Katzenberg recently lamented the dearth of holiday-themed movies headed to your multiplex this year. But in foisting “Rise of the Guardians” upon unsuspecting audiences for the holidays, it’s clear he just wanted some cover. Other holiday films would take some of the pressure off this joyless, soul-dead piffle.

“Guardians” is the worst animated movie to ever wear the DreamWorks logo.

It’s based on William Joyce’s “The Guardians of Childhood” books, about a team that includes The Easter Bunny, given an Aussie accent by Hugh Jackman here; “North,” aka Santa, made all Slavic and silly by Alec Baldwin; The Tooth Fairy (Isla Fisher) and the silent, roly-poly Sandman.

They need the help of newcomer Jack Frost (Chris Pine) if they’re to have a prayer of stopping “Pitch,” short for “Pitch Black,” the night-terror voiced by Jude Law. He’s seeing to it that kids across the world are giving up their belief in magic and magical figures like themselves. And he’s giving them night terrors.

All the Guardians have their public face, and their commando side. When action is called for, they team up to save childhood. Is Jack Frost worthy of their ranks? He’s an imp, a bit of a rogue, more into mischief than making the world safe for dreaming. He freezes this and that and makes with the mayhem. Kids, who can’t see him — only his handiwork, don’t mind.

North sees the threat that Pitch’s “touch of fear” carries, and summons his unruly troops.

It’s a confused ramble across some of the same ground covered by “Arthur Christmas,” “Monsters, Inc.” and “The Tooth Fairy,” a film more concerned with the mechanics of how Santa manages to make all those toys — he has zany, nonspeaking Yeti and elf assistants — than with telling an interesting story or giving the characters anything much warm or funny to do.

“Rise of the Guardians” is harmless enough, and the lack of easy pop-culture jokes represents the post-“Shrek” direction of DreamWorks well enough. But this is the studio’s least entertaining film. For a company that banks on building franchises of kiddie cartoons, from “Shrek” to “Madagascar,” these Guardians don’t rise to the occasion — not by a long shot.
