Sienna Miller Brings Daughter Marlowe, 11, to Horizon Premiere at Cannes Film Festival
Sienna Miller attended the world premiere of 'Horizon: An American Saga' on May 19 with her 11-year-old daughter Marlowe and boyfriend Oli Green.
Miller's upcoming movie Horizon is directed and co-written by Kevin Costner, and "chronicles the incredible epic journey of the expansion of the American West, before and after the Civil War," according to a synopsis. "In a flamboyant fresco where multiple destinies intertwine, dreams and hopes face obstacles and cruelty to offer a cinematic spectacle of exceptional scope and emotional depth." Costner, 69, attended the event accompanied by five of his seven children on the red carpet: Annie, 40, Cayden, 17, Grace, 13, Lily, 37, and Hayes, 15 — the latter of whom appears in Horizon alongside his father.
