Review: Passion spills over in the loose-limbed ‘Erupcja,’ starring Charli XCX

Film buffs understand that nearly every movie is, at heart, a travelogue — even if it occurs in your neighboring town — and that most travelogues can come across like love stories, whether anyone ends up together or not. That’s the whimsical, charged appeal of the Charli XCX-starring “Erupcja,” a mélange of romance, escape and disruptive coincidence in modern Warsaw from American micro-auteur Pete Ohs.

If you put footage of a smoke-spewing volcano under that Polish title, you’ll gather what the word means, which is exactly what Ohs does at the beginning, color-tinting his boxy frame ’60s-arthouse-style and adding a vintage Mancini-esque track from a Polish chanteuse. All the better to seed the belief that we’re about to experience something dreamy and convulsive.

That said, a volcano isn’t why British couple Bethany (Charli XCX) and Rob (Will Madden) have arrived in Warsaw. That rumbling you hear could also just be suitcases rolled over ancient streets. Besotted Rob’s surprise plan was to propose to Bethany in Paris — as revealed to us in omnipotent voice-over (by Jacek Zubiel) that fills in the feelings and backstories of our protagonists.

Bethany chose Warsaw, however, because she has a rekindling in mind, in the form of her longtime friend Nel (Lena Góra), a florist for whom Bethany’s unprompted arrival under her balcony one night — stealing away from her Airbnb with Rob — is complicated and exciting. With the news breaking that Italy’s Mount Etna has just erupted, grounding planes across Europe, a mighty passion they forged as teenagers, fueled by drugs, clubbing, heart-to-hearts and poetry, has once more been unleashed. It’s just their thing: Whenever Bethany and Nel connect, a volcano announces itself somewhere in the world. Woe be to the moony boyfriend or, in Nel’s case, exasperated girlfriend (Agata Trzebuchowska), left behind to dust off the ash.

“Erupcja,” which Ohs also photographed and edited with impressionistic verve, unfolds as if Jacques Rivette’s playful air of mystery and Roberto Rossellini’s earthy melancholia had somehow come together to form a zillennial with a restless heart. Ohs makes movies with the in-the-moment creative participation of his cast — he, Charli, Madden, Góra and playwright Jeremy O. Harris, who portrays a friendly American artist, are the credited writers and the whole enterprise goes down like a cocktail of ruminations and swerves invented on the spot, but not haphazardly.

You get the buzz (music by Charlie Watson and Isabella Summers plays a big part), the hangover, but also an aura of remedy and renewal. It’s all very human, evident in the pop star’s subtly frisky portrait of someone drawn to abandon (Charli should definitely continue acting), but also in Madden’s unshowy, mature hurt and in how Góra suggests the more grounded half of a self-mythologizing duo. Ohs works in evocative details: inserted frames of color, like mood flashes, or a shot of a lonely phone ringing, never getting picked up.

He leaves it up to you to wonder if Bethany and Nel have ever been more than friends — “It’s not Romeo and Juliet,” Nel coolly declaims from her balcony upon glimpsing Bethany waiting below — but what’s fun is how that’s ultimately beside the point. The edgy appeal of “Erupcja” is in the way it maps humans as molecules and electrons, fizzed by location, inspired by connection, driven to hover, fuse and release. The characters may get bounced around a bit and some will feel stranded, but you’ll know you’ve been taken somewhere new by this charming indie.
