In my review of Robert Rodriguez's film Machete Kills I speculated that Quentin Tarantino introduced a small reference to Grindhouse movies in Once Upon a Time... in Hollywood to fulfill a rather outlandish promise from the fake trailer of Machete 3 in the beginning of Machete Kills. That there would be a Grindhouse movie with Leonardo DiCaprio. I think Paul Thomas Anderson just beat Tarantino in this regard. His 2025 film One Battle After Another ( starring DiCaprio ) is a straight up remake of the first Machete.
An exploitation film is a film that exploits some talked about fear or trend in culture in order to sell tickets to a movie that is probably not very good. Exploitation films are usually low budget, badly made B-movies, with a certain charm to them, if you like Tommy Wiseau's work. 2010's Robert Rodriguez film Machete is, somewhat of an intentional attempt at recreating the exploitation film phenomenon. Which exploits US politics of 2025, somehow. ( Rodriguez must have a time machine somewhere in his studio ).
