Another Earth (2011)

Every choice we make ripples outward in ways we can't always see. Mike Cahill's "Another Earth," co-written by and starring Brit Marling, opens on the night a mysterious second Earth appears in the sky. Rhoda Williams (Marling), a bright 17-year-old headed for MIT, is so distracted by the sight that she causes a car crash that kills the wife and young son of John Burroughs (William Mapother), a gifted composer. Four years later, released from prison and consumed by guilt, Rhoda seeks out the grieving John, now a recluse, and, unable to reveal who she is, begins working as his housekeeper. As an unexpected bond forms between them, the mirror planet draws closer, and Rhoda learns of a chance to travel there - raising the possibility of another life, another destiny and another self. A winner at the Sundance Film Festival, it's quiet, haunting and unforgettable, with an ending that will stay with you.
