This feels like it could be Michelle Williams’s best work, portraying the iconic Marilyn Monroe who comes to Britain for "The Prince and the Showgirl" alongside Sir Laurence Olivier, played by Kenneth Branagh. Simultaneously, Colin Clark, an aspiring screenwriter portrayed by Eddie Redmayne, is trying everything he can to break into the film business, persistently approaching producer Hugh Perceval, brought to life by Michael Kitchen. Eventually, he manages to get a start, and a connection with Sir Larry leads to one with Monroe; soon, young Clark finds himself responsible for keeping this increasingly unreliable woman on track because her approach isn't exactly as structured or dedicated as Olivier’s. Those familiar with the 1957 film will know it wasn’t necessarily anyone’s best work—with the possible exception of Dame Sybil Thorndyke, portrayed by Judi Dench, who offers the American visitor a degree of understanding and acceptance amidst rising tensions, as the dynamic between Colin and Marilyn deepens. The story is drawn from Clark's two books about the experience, so it does provide a genuine and thoughtful look at how that single week unfolded; how these different personalities and their ways of working struggled to align. Williams seems very natural in the role of the troubled actress, as does Branagh, who convincingly embodies an Olivier accustomed to having things his way. Redmayne doesn’t make much of an impression—perhaps because his character needs to remain detached as a narrator, and Clark wasn't eager to fictionalize his own involvement, however close it may have been, with Monroe. Both she and Olivier are compelling figures in film history, and this biographical film gives us a peek into how creative conflicts can sometimes produce something worthwhile.
