Star-crossed in the Mideast

The title of Israeli writer-director Eytan Fox’s new film, “The Bubble,” is a pejorative reference to youthful myopia, namely in the trendy Sheiken Street district in modern Tel Aviv, where twentysomething progressivism may feel more like a cool romantic spirit than something politically urgent.

For the trio of mixed-orientation roommates -- romantically volatile T-shirt designer Lulu (Daniela Wircer), flamboyant cafe manager Yali (Alon Friedmann) and soft-spoken record store worker Noam (Ohad Knoller) -- who share a cramped apartment and a sexy liberal lifestyle, the Palestinian-Israeli crisis bites, but a turbulent love affair or bad taste in music is more likely to provoke an endless discussion.

Of course, with a title like “The Bubble,” something is going to burst, and it starts when Noam falls for Ashraf (Yousef “Joe” Sweid), a sweet-faced Palestinian man he first met as a weekend reservist on checkpoint duty. Spurred by the notion that Ashraf would rather stay in their love-one-love-all clique than with his conservative family in Nablus -- where his sister is set to marry a militant member of Hamas -- the three get him a Hebrew name and a job at Yali’s restaurant and include him in their plans to throw an anti-occupation rave at the beach.

Ashraf and Noam love each other, but as Ashraf’s particular pressures mount -- being gay in a homophobic Arab culture, feeling caught between two nations, but perhaps more urgently needing to avoid capture as an undocumented Arab -- he starts to withdraw, and suddenly the frisky idealism of Noam and his friends begins to feel like a dangerous cluelessness.

In one sharply conveyed sequence, Lulu and Noam pretend to be credentialed French journalists so they can get through a checkpoint and look in on a scared Ashraf hibernating in his Arab community. Although their ruse threatens to expose Ashraf’s double life, their demeanor is that of role-playing children on a lark.

Content to flit between light comedy, eroticism and relationship operatics for much of the time, director Fox -- whose previous films include the controversial gay Israeli soldier tale “Yossi & Jagger” -- gives his beautiful dreamers plenty of leeway to win us over. To that end, he’s assembled a vibrant, brimming cast and given the talented Sweid a role that brings out all that is liberating and terrifying about a conflicted soul trapped in an ancient standoff.

It’s only when “The Bubble” takes a swift turn into domino-tipping tragedy in the final act that a tender, fraught love story feels casually discarded in favor of something psychologically pat and ham-fistedly earth-shattering. Ironically, for an otherwise engaging look at where politics and the personal confusedly intersect for a generation of youth trying their best to keep the grimmer realities of their world at bay, it’s the only real false note.
