Convicted paedophile Gary Glitter is set to receive a paycheck as one of his hits features in the Joker movie.
The single Rock and Roll Part 2 plays for around two minutes in one of the movie's key scenes.
Joaquin Phoenix, who is tipped for an Oscar for his take on the DC Comics villain, is seen dancing to Glitter's single down a staircase after completing his transformation into the murderous clown.
Experts say Glitter will be paid a lump sum for the inclusion of his 1972 hit and will receive paid royalties in relation to the success of the movie at the box office and sales of the DVD and soundtrack.
Moviegoers have been venting their frustration at hearing of the film's link to the notorious child sex offender.
"Whose idea was it to play f*****g Gary Glitter in Joker?" tweeted one.
"How did that get through the editing process?" another demanded to know.
While a third sarcastically tweeted: "Big ups to Joker and [director] Todd Phillips for using a Gary Glitter song and giving money to a known peadophile."
Glitter, real name Paul Gadd, is currently serving a 16 year sentence after being convicted of abusing three young girls.
He was found with thousands of indecent images on his laptop during the 1990s, and was thrown out of Cambodia for suspected child abuse in 2002.
After a hugely successful opening weekend, Batman spin off Joker surged into the box office record books.
The dark psychological thriller smashed October records, after raking in £114 million internationally.
Though, for some, the film proved too scary with some film fans tweeting they'd walked out of the cinema claiming it was 'too dark'.
Though others have praised the new film for highlighting mental illness.
But the film has sparked controversy since it was first released, as critics believe the dark violence could create copycat crimes.
