They Call Me Trinity (Italian: Lo chiamavano Trinità...) is a 1970 spaghetti Western comedy film written and directed by Enzo Barboni (under the pseudonym of E.B.

The film stars the duo of Terence Hill and Bud Spencer as half-brothers Trinity and Bambino, who help defend a Mormon settlement from Mexican bandits and the henchmen of the land-grabbing Major Harriman.

Trinity, a lazy, ne'er-do-well gunfighter with unnaturally fast drawing ability and marksmanship, is dragged on a travois by his horse to a way station and restaurant.

The pair reach a small town, where they witness the local sheriff, a large, burly man with a similarly fast drawing ability to Trinity, gunning down three men after they harass him for not allowing one of their criminal friends to be released.

However, the two form a temporary partnership to deal with Major Harriman, who is attempting to run a group of pacifist Mormon farmers off their land with the intention of using their property to graze his own horses.

The fact that these horses are valuable and unbranded explains Bambino's grudging willingness to work with his little brother, even though he considers Trinity to be a shiftless bum without ambition.

[14][15] In a review published by Time Out, the film is called "first and best in the Trinity series of spaghetti Westerns, rare in that it is successful in combining laughter and some degree of interest in the action".

[16] In his book Once Upon a Time in the Italian West: The Filmgoers' Guide to Spaghetti Westerns, author Howard Hughes writes "They Call Me Trinity is Hill and Spencer's finest vehicle".
