Through the end of November, Hulu is hosting Sergio Leone’s Dollars Trilogy for free viewing: A Fistful of Dollars, For a Few Dollars More, and — the greatest, obviously — The Good, the Bad, and the Ugly. Since the films are for mature audiences, you must register an account to watch.
The Hulu collection is actually called “Clint Eastwood Westerns,” so you can also watch Hang ‘Em High, which — bit of trivia here! — was the first film produced by Clint Eastwood’s production company, Malpaso Productions, then known as the Malpaso Company.
