Day of the Evil Gun is a 1968 film Western starring Glenn Ford, Arthur Kennedy, and Dean Jagger. It was directed by Jerry Thorpe.
Former gunslinger Lorn Warfield (Ford) returns home after three years absence to find his ranch in ruins and learns that his wife and children were abducted by an Apache raiding party. Though he has renounced violence, he now takes up his gun again and does in search of his family. Unwillingly, he accepts the help of his neighbour Owen Forbes (Kennedy) on his quest. Complicating matters, Forbes is engaged to Warfield's wife, who believed her husband was dead. Along the way, they run into Mexican bandits, army deserters and Apaches.
- Agony of the Feet: When Warfield tries to walk away from Forbes at the end of the film, Forbes shoots him the ankle with a shotgun.
- Army Scout: One of Addis' band of Dangerous Deserters is an Indian scout whom he sends to negotiate with the Apaches. The Apaches send back his body.

It turns out that Addis, who is actually a corporal, and the rest killed the real captain so that they could trade two wagons full of weapons and ammunition to the Apaches in return for an army payroll the latter recently captured.
- Faux Affably Evil: Bandito leader Jose Luis Gomez de la Tierra y Cordoba DeLeon likes to play the Spanish grandee. While he is always impeccably dressed and unfailingly polite, he is also utterly ruthless and has no issues with dealing in slaves or leaving someone staked out in the desert to die a slow agonizing death.
- Frontier Doctor: Warfield and Forbes arrive in a small town where they are hoping to resupply and gather intelligence about the location of the Apache camp. However, they town is in in the the grip of a cholera outbreak. The town doctor is run off his feet not only attending to the sick, but burning the homes and possessions of those who have died.

- Interrogation by Vandalism: Warfield gets Noble to drop his Obfuscating Insanity by starting a fire under his wagon and not allowing him to move it until he spills what he knows about the Apache. Later, Forbes uses an almost identical tactic against the storekeeper in the cholera town: soaking his store in kerosene and threatening to drop a lit match unless he he tells him where the Apache camp is.
- Knows the Ropes: When they are being pursued on horseback by the Apache, one brave lassos the Winchester out of Warfield's saddle boot, while another lassos his revolver out of his hand.
- Molotov Cocktail: Warfield uses a kerosene lantern as an improvised Molotov cocktail to set fire to ammo boxes in the Apache camp.
- My Greatest Failure: Forbes eventually reveals that the reason he is hellbent on accompanying Warfield on his quest to rescue Angie and her children, despite Warfield not wanting him there, is beacuse he was on his way to see Angie on the day she was taken and, when he saw the Apaches attacking the ranch, he hid in a ravine and watched as the Apaches captured Angie and the two girls and rode off. Even though he knows he could not have saved them, and trying to do so would almost certainly have got him killed, the guilt of his inaction haunts him.

- Shoot the Messenger: Addis sends his Indian scout to negotiate withe the Apaches to exchange the stolen payroll for the two wagons of ammo. The Apaches respond by sending back the scout's body.
