On Chesil Beach.

I read Ian McEwan’s Atonement back in 2007 but strongly disliked how manipulative the narrative turned out to be, so I skipped the highly acclaimed film adaptation that came shortly after, with a then-unknown 13-year-old actress named Saoirse Ronan playing one of the pivotal roles in the movie. Ronan is now, of course, a three-time Academy Award nominee, including one nod for Atonement, and returned to McEwan’s milieu as the star of this year’s adaptation of his novella On Chesil Beach (amazon • iTunes), which covers familiar thematic territory but does so without the trickery of the earlier work, and builds slowly to a crescendo finish that ends with an gut-punch conclusion that speaks volumes with very little dialogue to punctuate it.

On Chesil Beach is an ostensible love story between upper-class Florence (Ronan) and working-class Edward (Billy Howle), told mostly via flashbacks on their wedding night as the two approach their first time in bed. A sweet, awkward romance emerges in scenes from their courtship, including stories of her frigid mother and angry, distant father, as well as images of his difficult childhood with a mother who suffered brain damage in an accident and has trouble with memories and with some basic social graces (including, as it turns out, wearing clothes when required). It eventually comes out that Florence’s wedding-night jitters are more than just tremors of anticipation, but that there is something extremely wrong beyond mere ignorance of the mechanics of sex. When Edward makes his first, clumsy attempt, the flashbacks turn darker – apparently the reason for her terror is clearer in the movie than the book – and the tone of the film turns abruptly into one of regret and shame for Edward as he details his life after the wedding night.

As with Atonement, one character’s rash decision in youth affects multiple lives, but here there is no pretense or deception on McEwan’s part – we know what happened in the ‘real time’ of the script, and there’s no sleight of hand to mislead us. For me, at least, that made the final half hour, from the wedding night, the revelation (to us, but not to Edward) of Florence’s past trauma, and the jumps forward to Edward’s future without Florence gutting to watch, as he realizes what his reactions in the heat of the moment – both out of anger and shame – have cost him over the remainder of his life.

Music is a recurrent theme in On Chesil Beach as well, including the use of classical music (Florence’s passion, as she plays in a string quartet) and early rock and roll (Edward especially loves Chuck Berry) to further distinguish the two main characters’ class differences. There’s also a scene about adding a fifth member to the group where we see a totally different side of Florence, a stronger, almost domineering presence at the head of the quartet, in full contrast to the timid woman shown in intimate scenes with Edward, as if to make clear that she’s not a nervous or weak person, but is repressed in a specific situation for a specific reason.

Ronan is superb, as always, although there are certainly scenes here where she’s reduced a bit by stilted dialogue to standing around in cute dresses; her character is by far the more pivotal of the two, and requires more restraint than the role of Edward, whom Howle plays as emotionally messy and underdeveloped, himself probably as unprepared for the institution of marriage and the responsibilities one has to a partner as Florence was for sex. The movie’s first hour or so is fairly slow going, I think by design, and some of the side characters are very thin, including Florence’s mother (played by Emily Watson), whose role in all of this could have used more explanation and whose attitude towards her daughters is itself hard to fathom.

At the 80 minute mark, I was sure I’d be calling On Chesil Beach a trifle, or even a bit dull, but the turnaround towards the end was so powerful that it forced me to reassess everything that came in the first 2/3 of the film. Nothing prepared me for how the story would wrap up, or how McEwan’s screenplay would shift the focus to make it clear that the blame isn’t on Florence, and that we’ve seen too much of the story through Edward’s eyes to understand how wrong he was to react as he did. The result is a potent, wrenching portrait of regret that also serves as a plea for understanding when someone we love needs it most.
