‘Brokeback Mountain,’ Onstage, Lacks Some Intensity

“This ain’t no little thing,” Jack Twist (Mike Faist) says of the depth of attraction he is experiencing in “Brokeback Mountain.”

But the rodeo cowboy could equally be referring to the ongoing life of Annie Proulx’s celebrated short story. First seen on the pages of The New Yorker in 1997, Proulx’s distilled account of a tragically foreshortened affair has been an Oscar-winning film, an opera and now a self-described play-with-music.

This latest iteration opened Thursday night in the @sohoplace theater in the West End, where it is scheduled to run through Aug. 12, offering a passing glimpse of some powerfully familiar characters. The bare bones of the narrative are there; the dramatically necessary flesh and blood and sinew are not.

I was pleased to renew my acquaintanceship with the gregarious Jack and the more indrawn, troubled Ennis del Mar (Lucas Hedges), the two men who begin a furtive relationship in 1963 while herding sheep in the rural Wyoming locale of the title.

But I’m not sure that the American writer Ashley Robinson’s adaptation actually deepens our understanding of material that many will inevitably associate with Jake Gyllenhaal and Heath Ledger in a lauded movie that lasts a good 45 minutes longer than the play (Jonathan Butterell’s atmospheric production clocks in at 90 minutes, no intermission).

Told piecemeal across 20 years, the play comes punctuated with an attractive sequence of original songs by Dan Gillespie Sells, the English musician with whom Butterell collaborated on the (very sweet) homegrown stage and screen musical, “Everybody’s Talking About Jamie.”

The seductive country twang of his music is punchily delivered here by the Scottish singer-songwriter Eddi Reader and an ace band visible at the side of the stage: look closely and you’ll see the pedal steel guitarist B.J. Cole, who has worked with Elton John and Joan Armatrading, among others.

The music exists to express emotions to which the men, and the women they marry, are reluctant to give voice outright. Reader, billed as the Balladeer, is granted an articulacy missing from the characters nearby onstage who live in their bodies and not their minds.

A standout number, “Sharing Your Heart,” comes at the point at which Ennis’s wife, Alma (a sympathetic Emily Fairn), realizes that her husband’s lasting affections lie elsewhere. In a separate track, lyrics describe “the lavender sky,” which a film can easily depict but which here has to be taken on faith. Tom Pye’s evocative set keeps closer to the ground, bringing to life kitchens, campfires and the tent inside which Ennis and Jack first allow themselves to be intimate.

The two seek shelter from the cold only to find further comfort in each other’s arms, and the tent shakes on cue to signal the carnal activity going on within it. What we don’t get, beyond stolen kisses, is the layered unfolding of a relationship with an intensity that takes the pair by surprise, so movingly evoked in both the original story and the film.

It’s one thing for Jack to look on, clearly intrigued, near the start of the play as Ennis washes himself. But the writing is too synoptic and the action too abbreviated to allow the full weight of what is happening between them to be felt.

“I ain’t no queer,” Ennis says early on, eager to disavow the feelings that will come to consume his life. What’s missing is time properly spent in the pair’s company, so that we feel the ebb and flow of this impossible romance. As it is, we get a sequence of highlights, a seeming annotation of the play rather than the thing itself, with the advancing years indicated by the ages of Ennis’s two daughters and Jack’s son. Mentions of the Vietnam War and the draft offer a perfunctory nod to the wider world beyond.

Onscreen, of course, you can age up the actors on the way to the story’s bleak conclusion. The innovation here is to recast the story as a memory play, with the Older Ennis (a grieving Paul Hickey) on hand throughout to show the continued impact of Jack upon Ennis. The effect, at least for me, was to cast a glance back to Sam Shepard’s “Fool For Love,” another play about a combustible relationship defined by a character named solely as The Old Man.

The two leads, in their West End debuts, acquit themselves well given the formidable challenge posed by their screen forbears. Hedges may not have the immediate physical command that Ledger had onscreen, but he shares his late predecessor’s furrowed brow and a sense of roiling anguish at society’s intolerance, and to some degree his own. This is someone who will never know peace.

And Faist, so memorably springy and vital as Riff in the Steven Spielberg remake of “West Side Story,” is really wonderful: engaging and likable from the start, only to reach a psychic abyss on the way to Jack’s signature comment to Ennis: “I wish I knew how to quit you.” Pausing to play a mean harmonica, Faist more than justifies a play that can otherwise feel a tad superfluous.

You may or may not weep at this “Brokeback” — I did not — but just as Jack is to Ennis, I expect Faist’s performance will be impossible to forget.
