Malatesta's Carnival of Blood (1973)

None.

Although the film is violent, most of the gore comes off as fake due to the film's low budget. Some bloody deaths include a man being decapitated on a roller coaster, a man beaten, one stabbed with a knife embedded in his chest on the ferris wheel, one stabbed in the head with blood spewing down his face, a woman getting blood drawn through a syringe (wherein we get a clear look at the bleeding arm), a man getting stabbed in the eye and another one is drowned whilst gagged and tied.

Very mild language, if any: one use of shit and hell.

None.

Nothing too frightening, apart from the violence and the film's bizarre tone.
