Actor John Simm says it “explained a lot” when he discovered on the ITV show DNA Journey that his deceased father, Ronald Simm, was not his biological father.
His biological father was a club manager named Terence, whom Simm had met several times when his band played at clubs that Terence managed.
Simm, who has appeared on Life On Mars and Doctor Who, described the revelation as "vindicating", explaining feelings of difference from his family and his decision to leave home at 16.
He admitted the discovery "spun his world" and considered quitting DNA Journey, but ultimately used the show's resources to learn about Terence.
Simm learned Terence is deceased and that his mother and Ronald had separated and reconciled before his birth, a detail previously unknown to him.
