"Day of the Badman" is a decent film and it stars Fred MacMurray...which isn't bad. But it's also a completely unnecessary film as the plot is essentially a reworking of "High Noon"....so why not just watch "High Noon"?!
When the film begins, you learn that a man was convicted of murder and is awaiting sentencing. However, his family comes to town and begins an intimidation program aimed at getting the guy only a slap on the wrist instead of a proper hanging. Over time, the good townsfolk turn out to be yellow and would rather let the killer go than face the wrath of his scum-bag kin. The only one standing in the way is the Judge (MacMurray).
The only real difference between this and "High Noon" is the subplot about the Judge's girl making time with the Sheriff. This clearly isn't enough reason to merit making the film but is mildly interesting. Competently made but lacking originality.
