Melchiorre kills Pedru because his elm tree imposes over his land and kick starts a ‘faida’ (blood feud) between the two families. Andria seeks revenge for the murder of his brother and goes hunting Melchiorre in the mountains, against the wishes of his family who desperately need his help managing the farm during a particularly brutal drought.

Born in Torpè, a province of Nuoro in Sardinia, Edoardo Mulargia made his directorial debut with Le Due Leggi in 1962 and went on to direct a number of westerns throughout the 1960s and 70s. It’s worth noting that Le Due Leggi plays out just like a western in many ways, both stylistically and thematically, with family feuds, shootouts in mountains and bandits in hiding becoming some of the typical traits of the genre that would emerge a few years later. To call it a prototype European western wouldn’t be far from the truth…

Producer Gisleno Procaccini started out selling coffee machines before graduating to selling bar furnishings and was considered something of an anomaly in the field of Italian cinema. Active in the 1960s and 70s he was introduced to the film industry by his friend, the actor Walter Brandi, a native of Pergola. In 1962 Procaccini financed two films, Slaughter of the Vampires directed by actor-turned-director Roberto Mauri and The Two Laws directed by Edoardo Mulargia, also starring Brandi. He then tried his hand at acting in Arriva Durango, Paga o Muori under the pseudonym Gis Cooper. His adventures in cinema ended two years later with just six productions under his belt. (source)
