Indiana Jones and the Kingdom of the Crystal Skull (2008)

CANNES, France — “Indiana Jones and the Kingdom of the Crystal Skull” is a movie for boomers of all ages, though you can bet the bank that plenty of tots will be tagging along with Mom and Dad, Granny and Gramps. Like the 1981 blockbuster “Raiders of the Lost Ark,” the first in a monster franchise that has spawned two previous movie sequels, a television series, comics, novels, video games and Disney theme-park attractions, this new one was directed by Steven Spielberg, cooked up and executive produced by George Lucas (with Kathleen Kennedy) and stars Harrison Ford as the archaeologist-adventurer-sexpot with the sardonic grin, rakish fedora and suggestive bullwhip.

This latest Indy escapade, which was shown out of competition at the Cannes Film Festival and will probably scoop up more money than the rest of the selections combined, serves as a reunion for the principal creative team. Almost two decades have lapsed since the third installment in the series, “Indiana Jones and the Last Crusade” (1989). In the years since, Mr. Lucas — whose logo for Lucasfilm received the loudest applause at the press screening in Cannes — continued to build his special-effects empire and resurrected the “Star Wars” franchise while Mr. Spielberg has oscillated between serious-minded projects and financially instrumental entertainments.

For his part, Mr. Ford rode the ups and downs of high-concept stardom, oscillating between roles that called for him to flash his customary wry grin or his equally familiar grumpy frown. He wears both in “The Crystal Skull,” though the busy story makes enormous effort to keep the mood happy and snappy and decidedly PG-13 friendly — P.C. friendly, too, as in politically correct, with fewer dark-skinned people popping their eyeballs. Not that Indy has gone soft or the natives have gone hard, mind you, only that Mr. Spielberg no longer seems as eager to cut down extras for a laugh.

Thank goodness for the fall of the Soviet Union and the rise of Vladimir V. Putin, which have expedited the return of blond-haired, blue-eyed villainy to the screen. Set in 1957, this new Indy yarn, written by David Koepp from a story by Mr. Lucas and Jeff Nathanson, takes place far from the Middle East even if it opens in a desert. The bad guys this time are cold war Reds first seen poking around an American military base and led by Irina Spalko. A caricature given crude, playful life by Cate Blanchett, Irina owes more than a little to Rosa Klebb, the pint-size Soviet operative played by Lotte Lenya, who took on James Bond in “From Russia With Love.”

Dressed in gray coveralls, her hair bobbed and Slavic accent slipping and sliding as far south as Australia, Ms. Blanchett takes to her role with brio, snapping her black gloves and all but clicking her black boots like one of those cartoon Nazis that traipse through earlier Indy films. She’s pretty much a hoot, the life of an otherwise drearily familiar party. Among the other invited guests are Ray Winstone, John Hurt and Shia LaBeouf, who plays Mutt, the young sidekick onboard to bring in those viewers whose parents were still in grade school when the first movie hit. Karen Allen, who played Indy’s love interest in “Raiders,” is here too, with a megawatt smile and a bit of the old spunk.

If only the filmmakers seemed as eager to see — and to please — the audience as Ms. Allen. There’s plenty of frantic energy here, lots of noise and money too, but what’s absent is any sense of rediscovery, the kind that’s necessary whenever a filmmaker dusts off an old formula or a genre standard. “Raiders of the Lost Ark” creaks with age now, but to look at it again is to see Mr. Spielberg actively engaging in an organic whole, taking a beloved template and repurposing it for the modern blockbuster age he helped create. By contrast, “The Crystal Skull” comes alive only in isolated segments, in a clever motorcycle chase that ends in a library and, best of all, in an eerie sequence at an atomic test site that wittily puts the nuclear in family.

The original Indiana Jones venture was inspired by Mr. Lucas and Mr. Spielberg’s love for 1930s serials, but you’d be hard pressed to find much inspiration in their latest collaboration. There’s plenty of perspiration, of course, what with the wall-to-wall chases — many tricked out with obvious computer-generated effects — that careen one into another like colliding big rigs. As expected, the high leaps and long jumps look impressive, even if it’s something of a bummer when one of the best directors working today (Mr. Spielberg) doesn’t seem to be working as hard as the stunt crew. Initially, I thought he was bored with the material (he wouldn’t be alone), but now I think he’s just grown out of this kind of sticky kids’ stuff.

Creative ennui certainly might explain why he spends so much time riffing both on his own greatest hits — Indy and company have an encounter of a close, insipid kind — and on other movies. Some of these allusions amuse (a sea of red ants parting à la “The Ten Commandments”) while others are just painful (Mr. LaBeouf done up to resemble Marlon Brando in “The Wild One”). It’s odd to see Mr. Spielberg recycling plot points already chewed through by Roland Emmerich in “Stargate,” though Indy’s brief encounter with some ferociously feathered Indians who look right out of Mel Gibson’s “Apocalypto” was a tantalizingly sweet pip, a sequel in waiting (“Indiana Jones Meets Mad Max”) or maybe just a YouTube mash-up.

“Indiana Jones and the Kingdom of the Crystal Skull” is rated PG-13 (Parents strongly cautioned). Death, but little blood.
