Newcomer Connor McCarron has won acclaim for his role as a youth who becomes embroiled in gangland violence in the 1970s in new movie Neds.
The 17 year old recently claimed his father, John, was a "role model" who kept him away from dangerous gang culture as he was growing up.
But the actor's comments have now come under fire from grieving parents Ronald and Helen Auld, whose son William was stabbed to death by John McCarron following an argument in a Glasgow bar early last year (10).
He was sentenced to a minimum of 18 years behind bars last August (10).
Ronald Auld tells Britain's Daily Record, "Connor was saying his dad was a role model and that got us upset. His father is doing 18 years for murder."
