Jude Law, Sydney Sweeney in Ron Howard Survival Pic

It would be completely understandable that Ron Howard, having directed more than two dozen genre-tripping films spanning six decades, would want to shake things up a bit by jumping into something outside his proven comfort zone.

And it would be equally logical that the vehicle to take him there would be a certifiably bizarre but true account of a 1920s German philosopher who sets up an experimental society with his lover/disciple on a remote island in the Galápagos, only to have it all implode when opportunists come and crash the party.

But despite all the intriguing possibilities of the concept and a game, international cast including Jude Law, Ana de Armas, Vanessa Kirby, Daniel Brühl and Sydney Sweeney, Eden, handed its world premiere at Toronto, never finds its happy place. The prevailing overwrought tone lands more cartoonish than satirical, while a protracted running time accentuates the film’s deficiencies.

The movie certainly starts promisingly enough, efficiently setting up the life and times of Dr. Friedrich Ritter (Law). In 1929, he flees German society and its bourgeois values to create a new home on the remote island of Floreana, living off of limited natural resources with his survivalist partner, Dore Strauch (Kirby).

But the couple’s solitary existence is interrupted by the arrival of Heinz Wittmer (Brühl), a World War I vet with a younger new wife, Margaret (Sweeney), and a son, Harry (Jonathan Tittel). They have been following Ritter’s dispatches and hope the land’s virgin air might cure Harry’s tuberculosis, just as it appears to have kept Strauch’s multiple sclerosis under control.

Feeling less than hospitable, Ritter and Strauch glare at the newbies with their safari shorts and butterfly nets, figuring they won’t make it until the first rains.

But while the family prove surprisingly resilient, building a home for themselves and their soon-to-be newborn, their co-existence is freshly threatened by the entrance of the Baroness Eloise Bosquet de Wagner Wehrhorn (de Armas), accompanied by a pocket harem of young men, who intends to build the world’s most exclusive resort on the rocky terrain.

It soon becomes clear that the Baroness, with her long strand of pearls and a hard-to-place accent that sounds much like Anna Delvey’s, is a scheming instigator. She proceeds to pit the inhabitants against each other, leading to an inevitable descent into madness.

Despite an inspired setup that might suggest Werner Herzog’s Gilligan’s Island, Howard and screenwriter Noah Pink (Tetris) shipwreck the Queensland-shot vehicle in a mishmash of styles. Neither quite satire nor thriller nor murder mystery, the film cries out for a sharper attack.

It’s the kind of tale that would have been a natural fit for the likes of Mike White, whose acutely devious White Lotus sensibility would have been right at home here. But although Howard delivers some effective set pieces, notably a harrowing sequence in which Margaret must deliver her own baby, little about Eden feels consistent.

As a result, the performances are likewise hit and miss. De Armas does the best she can with her femme fatale role, even though she ultimately lacks the satirical chops of a more seasoned character actress to really hit it home.

Meanwhile, Law (so commanding in another TIFF offering, The Order) grows so tiresome as the smug, pontificating Dr. Ritter that by the time he eventually loses his mind, you can’t blame it for wanting to get away.

Only Sweeney manages to retain the viewer’s sympathy and her character’s sanity as the decent pillar of stability that is Margaret — who, as the end credits and archival footage reveal, would remain on the island until her death in 2000, and where her descendants host tourists at Wittmer Lodge to this day.

Now that premise sounds more like something in Howard’s wheelhouse.
