Naomi Watts and Bill Murray lead The Friend, an adaptation of Sigrid Nunez's novel about a woman who adopts her late best friend's Great Dane.

Directed and written by David Siegel and Scott McGehee, The Friend sees Watts starring as Iris, whose mentor Walter (Murray) leaves four-legged pal Apollo (played by a Great Dane called Bing) to her in his will. He's a large dog and an even larger reminder of the person she's mourning, so their bond is a little rocky to start. But, as the Sharon Van Etten-scored trailer indicates, isn't that always the start of a beautiful friendship?

The cast also features Carla Gugino (The Fall of the House of Usher), Constance Wu (Hustlers), Noma Dumezweni (The Undoing), Ann Dowd (The Handmaid's Tale), Felix Solis (Unfrosted), Sarah Pidgeon (Tiny Beautiful Things), and Owen Teague (Kingdom of the Planet of the Apes).

The Friend hits select New York cinemas on March 28 before its wide release on April 4.
