Westwood, who also starred in BBC series Doctors, also used his status as an actor to abuse two teenage girls who had come to him for acting lessons and advice.
The court heard abuse against his first victim started when she was just six-years-old and he was 10, with prosecutor Andrew Wallace saying it led to years of “the normalisation of sexual abuse” which included touching her breasts and himself and making her watch pornography.
He also encouraged a young boy to touch himself as part of a “game” when he was 10 and Westwood was 18, and was “highly manipulative and controlling” to another woman who he held down “every few weeks”, and told her to lay there despite the victim telling him she did not want to have sex.
Judge Chawla said Westwood had “distorted sexual thinking”, adding: “You have failed to show any remorse and you have shown little or no insight into the impact of your offending had on your victims.
Sentencing, Judge Neil Chawla KC said Westwood had carried out “sordid sexual criminality” over an 11-year period and had been “nonchalant, bordering on arrogant” throughout the trial.
