I Fantastici Tre Supermen (1967)

From Wiki- The Three Fantastic Supermen was conceived during the period of a superhero film cycle during the mid-1960s in Italy.^[2] Howard Hughes described The Three Fantastic Supermen as being patterned after the film Superargo and the Faceless Giants.^[3] The director Gianfranco Parolini had worked in several genres including sword-and-sandal films where there are more than one hero helping each other achieve their goals. ^[2] He also commented on the stunts in the film, noting that they were done on set with actor Aldo Canti having to jump out of 20 feet high window, jump into a trampoline and jump into a truck which was moving at full speed.^[4]  Back to me:

I have talked about this movie a few times, but I really enjoy a lot of the posters made for it.  I wish I had seen them growing up, as they are enjoyable (the films in the series) and this first one was released theatrically.  I would have loved it!
