Think "Crash," with a gay orientation — lives of folks crisscrossing, some with disastrous results — over a sweaty and gritty 36-hour period in South London.

That's "Clapham Junction," the opening feature Thursday in the 20th Honolulu Rainbow Film Festival at the Honolulu Academy of Arts' Doris Duke Theatre.

A gay couple, Will (Richard Lintern) and Gavin (Stuart Bunce), get married in civil ceremonies, with a fancy reception.

Will disappears and has a quick liaison with Alfie (David Leon), a waiter, and gives the kid (unbeknownst to him, till later) his just-received wedding band as a guise to see him again.

Alfie goes to a gay bar when his shift is over, where Terry (Paul Nicholls) tries to pick him up.

At a public restroom, Robin (Rupert Graves), an employed screenwriter, is flashed by Julian (James Wilby), and they later meet at a dinner hosted by Belinda (Rachel Blake) and Roger (Tom Beard) ... that becomes boisterous with political blather.

Meanwhile, Theo (Luke Treadaway), a 14-year-old student, cruises the library history stacks with his eyes, eventually focusing on Tim (Joseph Mawle), a suspected pedophile, who happens to live in an apartment dwelling across the street from Tim's family.

Oh, and a black violin student who is feared by thugs keeps the secret to himself throughout the landscape.

That's the tapestry — frayed, colorful, beautiful, cloying — with some loose threads by the final credits.

The victim is the predator in one instance; there's public toilet sex, gay bashing in the park, constant lip locks, coke-snorting, nudity and other bizarre haps. The quick overlaps and editing from director Adrian Shergold, working from Kevin Elyot's revealing and exploitative script handsomely lensed, means adult fare from start to finish.

It's not for everyone, however, so approach with caution.

The film attempts to share real gay situations with some cliches, real straight lifers demonstrating infidelity and lack of responsibility — and even downright stupidity. 

It's possible that some viewers will get negative conclusions about gays from the film.

However, some elements — like the stalking antics of a very assertive teen in the film's most controversial seduction involving a suspected pedophile — shed light on wrongful assumptions by the parents of the child and viewers.

A predator could be a victim, too — compelling thoughts that should elicit both rage and trigger discussion.
