One of the most iconic, and influential, movies ever made, Sergio Leone’s monumental epic comes to 4K Ultra HD™. This edition includes both HDR-10 and Dolby Vision, restored from the original camera negative by Paramount’s archive team, L’imaggine Ritrovata and The Film Foundation, and personally scrutinized and signed off on by Martin Scorsese. Set in the dying days of the Old West, a struggle to control water in a dusty desert town embroils three hard-bitten gunmen in an epic clash of greed, honor, and revenge.
