A belated sequel to the 60s spaghetti classic with Franco Nero returning to the part he originated in a Colombian-shot Italian Western notable for its crazed plot ideas (Django, the genocidal gunfighter, has become a monk), and a pair of entertainingly loony supporting performances from the reliable Pleasence as a haggis-accented Scotch entomologist and, especially, Connelly as the villain, a mad Hungarian mercenary butterfly-collector who decorates his riverboat with the severed heads of his enemies and is fond of sweeping measures.
Nero broods and flashes his blue eyes, and his man-of-peace act ends after about three seconds when he unearths his trusty machine gun from his own grave. There's some exploitative violence and cartoony Third World politics and if it's not a patch on the original, it is at least consistently entertaining.
