The Outlaw Josey Wales is one of Clint Eastwood's finest Westerns – and it has a sequel that almost nobody has heard of. Westerns used to be one of the most popular genres in Hollywood, but around the start of the '60s, their popularity began to decline rapidly. Eastwood himself was one of the last major movie stars to make his name off the back of the genre, thanks to the Dollars trilogy and dark Western Hang 'Em High. Eastwood would go on to star in and direct many other "Oaters," capping off his run with 1992's Unforgiven.
