Due to a riot that happened in a movie house in Zamboanga back in 1971, this movie became infamous for starting the SOP of informing cinema owners ahead of time if Fernando Poe, Jr. will die or not. It is said that the cause of the riot was because FPJ's fans in a movie house in Zamboanga were frustrated due to the onscreen death of his character.
This was the second instance that Fernando Poe, Jr.'s character died onscreen. The first was on 1963 movie Sigaw ng Digmaan.
