Few filmmakers can bring a rut to life like Sofia Coppola. When her characters are in a funk, whether it´s a Hollywood actor in between jobs, a few lost souls in a foreign place or a Queen, it´s never the stuff of melodrama. She has an eye for the comedic banalities of the everyday like the excruciating awkwardness of a stilted conversation or, as in her latest ” On the Rocks,” the image of an overwhelmed mother trying to nap in the glaring sunlight while a Roomba bangs its way through the apartment. She turns her camera this time to Laura (Rashida Jones), a well-off writer living in a SoHo loft with two young daughters and a husband, Dean (Marlon Wayans) who lately has been distant, physically and emotionally, while launching his new business. Laura is getting by, dressing in a kind of uniform (Breton stiped shirts, denim and a gold necklace) and trying her best to cling on to signifiers of a once simple and nice life. But her days are spent in a rush from morning to night getting her daughters to school, to naps, to ballet, to dinner, to the bath and to bed. Her Chanel purse is almost never carried without a stroller and a canvas Strand bookstore tote bag along with it and her beautiful ceramic Dutch oven is now just for making instant mac and cheese. She´s also on deadline for a book that she has no time or will to write. Her few moments of quiet are spent rearranging her desk and making labels for ideas folders. So it´s almost a relief when she starts to suspect that Dean might be having an affair. He´s on the road a lot, he has an attractive, young and seemingly carefree co-worker, Fiona (Jessica Henwick), and, oh, then there´s the female toiletries that show up in Dean´s suitcase. Suddenly Laura has something else to focus on and her man-about-town father, Felix (Bill Murray), is more than happy to help enable the obsession.Murray´s Felix, a cool and charming art dealer who knows everyone and flirts with everything, sweeps in like a cool spring breeze to jolt Laura out of her routine and introduce a little chaos and spontaneity into her life with impromptu martini lunches (“Bombay for the kid”), birthday dinners at the 21 Club and SoHo House stakeouts in a smart red convertible with caviar (which they open) and champagne (which they don´t). Felix´s Manhattan is vibrant and exciting, and he glides through classic haunts and out of traffic tickets with an ease that Laura has never known.
