The credited name, Dick Spitfire, is a pseudonym for Diego Spataro,[6] a name that had also been used for an earlier film, Django and Sartana Are Coming...

D'Amato further recalled that Spataro, who had made many Spaghetti Westerns with Fidani, had plenty of stock footage from those films, and that some of it was used in editing Go Away!.

[4] In a contemporaneous review of the film, La Révue du Cinéma deplored mistakes in chronology, chaotic editing and lack of talent in storytelling, but at the same time recognized its quirky humour.

Lupi thinks that the film's best moments are its comic or "trashy" scenes, whereas he criticizes what he calls the "structural" parts: lengthy chases, laborious ambushes, endless, predictable shootouts and unrealistic brawls.

Still, Lupi applauds the last scene in which the Duke puts a hand of five aces on the table, calling it - in the Italian version - a "superpokermaggiore" (translated: "a major superpoker").
