Today’s cinema adventure: My Week With Marilyn, the wistful 2011 biopic based on Colin Clark’s memoir, The Prince, the Showgirl, and Me, which detailed the author’s brief relationship with iconic starlet Marilyn Monroe during the turbulent filming of The Prince and the Showgirl with actor/director Sir Laurence Olivier. Whereas many film biographies attempt to shed light on their subjects by presenting their life in its entirety, this charming true-life romance focuses instead on a short episode, using it as prism to cast insight into the legendary actress and her contemporaries. As a result, the film has an intimacy and an authenticity lacking in most Hollywood bios, and the narrowing of focus allows the performers to explore the nuances of their real-life characters with much greater depth and detail, heightening the illusion that we are watching real people instead of the larger-than-life caricatures to which we are so often subjected. Those performers, without exception, rise to the occasion: the entire ensemble clearly relishes its chance to embody this slice of mid-century mythology. The much-lauded Michelle Williams is largely successful in capturing the enigmatic persona that made Marilyn the biggest star in the world; she gives us the contrasting blend of sensuality and insecurity we expect but infuses it with a humanity that allows us to perceive the underlying causes of her fragility and need for validation, as well as the irresistible charm that won the hearts of so many. To be sure, her transformation is less than total- her physical attributes are not quite right, and her bearing sometimes seems mote timid than self-assured- but, of course, she is ultimately an actress interpreting a role, not a reincarnation, and as such she deserves much praise for conveying the essence of an oft-imitated woman who was, in fact, inimitable. Less glamorous, but perhaps even more impressive, is Kenneth Branagh’s work as Olivier which likewise captures the great actor’s outward persona with remarkable accuracy while showing the inner landscape of a man struggling to keep his place at the top in the face of changing standards in the art he has mastered for so long; Olivier was not only an early mentor for Branagh but an actor with whom his own career has often been compared, so he seems well-suited to the daunting task of personifying the legendary thespian- a task which he clearly relishes, recreating Olivier’s physicality and vocal patterns with intimate familiarity with0ut resorting to out-and-out mimicry, and treating his subject with obvious respect even when portraying some of his less attractive facets. As these two enact their clash of titans, they are surrounded by a host of worthy supporting performances, including Julia Ormond’s brief but canny portrayal of Vivien Leigh, Emma Watson’s decidedly non-Hermoine-esque turn as a wardrobe girl, and the always magisterial Dame Judi Dench as the always magisterial Dame Sybil Thorndike; but special praise should be reserved for Eddie Redmayne, who, stuck with the potentially thankless role of providing a foil for his co-stars, manages also to provide a solid ground for the proceedings by giving a quietly convincing performance as the young film crewman coming of age in the shadow of giants, and never lets us quite forget that this is, after all, his story. With all this great acting going on, it’s easy to overlook the film’s other pleasures- the meticulous costume and scene design; the rich, golden-hued cinematography by Ben Smithard; the understated archness of the screenplay by Adrian Hodges- all overseen by the steady hand of first-time director Simon Curtis, whose wise approach here is to step back and let all these elements leave their marks without the unnecessary assistance of showy cinematic trickery. The end result is a movie which, like the famous figure at its center, is lovely, effervescent, and hauntingly sad. It does not promise nor does it try to present the final word on Marilyn- or Olivier, for that matter- and for that very reason, probably comes closer to giving us a truthful, fair vision of these two legends than any scandal-raking exposé could hope to deliver.
