Despite the title, Hang 'Em High, starring Clint Eastwood, is not a particularly violent movie; in fact, it contains some moral scenarios that seek to capture the pioneering spirit (and the pioneering justice system) of the old Wild West.
The basis of the plot is that Jed (Clint) is hanged by an enthusiastic lynch mob of vigilantes who mistake him for a murderer and cattle rustler. Miraculously, he survives and is cleared of all charges when brought before a proper court of law. The poacher then turns gamekeeper as Jed becomes a Marshall and sets out for vengeance.
As well as being hanged, he is also gunned down at one point and is even attacked by an alsation dog - so, it's quite unusual to see Big Clint as vulnerable (and human) as he is here compared to many of his other offerings.
This is not a gritty tale. Hang 'Em High is actually rather wholesome (it includes romance, honour and a disillusionment with violence). This makes the film much more of a traditional type of Western rather than an alternative, or spaghetti, Western.
Moral undertones permeate this film (capital punishment, prison conditions, summary justice) and neither the acting or the soundtrack is particularly memorable.
Still, it's watchable, and if you're an Eastwood fan you'll find it to be a mildly amusing 110 minutes.
