Sophie Cook, who played Susan, recounted that a floor manager advised them to avoid Savile, describing him as a "kiddie fiddler", as he was working in an adjacent studio.
Cook suggested that the awareness of Savile's predatory behaviour was "culturally accepted" at the time, despite allegations emerging in the 1980s.
The BBC responded by referring to the Dame Janet Smith review, commissioned after Savile's death, stating they accepted its findings and implemented changes.
The cast also discussed other experiences during their reunion for the documentary 'Return to Narnia', including public scrutiny and hurtful negative press.
