They Call Me Trinity (1970) is the first of three comic spaghetti westerns directed by E.B. Clucher (Enzo Barboni) and starring Terence Hill (Mario Girotti). The others are: 1971s Trinity Is Still My Name! and 1972s Man of the East. All among my favorite Euro-Westerns.
They Call Me Trinity also stars the hulking Bud Spencer (Carlo Pedersoli) as the "brother" of Terrence Hill's Trinity. The two brothers meet up as Bud Spencer's character is impersonating a town's new sheriff under nefarious circumstances. It's from here the movie unfolds. A top notch midnight movie.
