Peter Foster, from Bridlington in Yorkshire, has been given two life sentences for murdering two of his partners 13 years apart, he was also given a total of 22 years in prison for seven counts of false imprisonment, kidnap and assaults on other women over a 26-year period.
Hull Crown Court was told Foster enjoyed dressing up like Alex DeLarge - the leader of a thuggish gang in the film A Clockwork Orange.
Both women died from blows to the stomach which, according to the prosecution, replicated the blow Alex DeLarge gave to a woman he murdered in the 1971 film.
In a letter to the judge, Foster admitted he was "a miserable excuse for a human being". But during the trial he had sought to deny the offences.
It took the jury three-and-a-half-hours to convict Foster of all the charges against him. These included the murder of Linda Grimm, 38, in July 1989 and Linda Wardill, 45, in December 2002.
Foster, who was a fairground worker, beat his partners to death - wielding an electric guitar to hit Linda Grimm.
Post-mortem evidence
The judge, Mr Justice Henriques, told Foster he was a very dangerous man and cruel to children and would be staying in prison for many years.
Foster left the dock clutching a bible which was the book Alex DeLarge read in prison.
Speaking after the case, Detective Superintendent Colin Andrews, of Humberside Police, said that because of incorrect post-mortem evidence in 1989 Foster had "literally got away with murder."
He added: "His offending goes back to 1968, but his violent offending goes back to 1973."
"He did have an interest in martial arts.
"The women said he dressed up in clothing from A Clockwork Orange."
