As Robert Rodriguez tells it, after conceiving of the character of Machete and telling Danny Trejo about it, Rodriquez started receiving phone calls at random hours of the day from Danny, trying to convince him to make the film. One day, Robert said to Danny that he was busy and asked why Danny can't just send a text message instead of constantly calling, to which Danny Trejo replied: "Machete don't text." Machete says this exact phrase in the film.
This film was made because of the popularity of a fake trailer for a non-existent "Machete" film that was featured in the theatrical version of Grindhouse (2007), along with other fake trailers and advertisements featured in the film. "Thanksgiving" is the other popular fake trailer included in the film and was directed by Eli Roth and it is in development to be made into a full-length film.

While filming "Machete", they were constantly competing for daylight, as the set for "Predators" would block out the sun for most of the day.
