London, Jul 6 : Late Brit actor Rob Knox's mother has revealed her pride for her son, after viewing an emotional private screening of `Harry Potter and the Half-Blood Prince'.

Sally Knox, 51, got her first glimpse of 18-year-old Knox playing Hogwarts pupil Marcus Belby at the private screening.

"Seeing the film made me feel immensely proud, but at the same time there's an underlying sense of sadness at Robert not being there to see it for himself," the Sun quoted her as saying.

London, Mar 8 : Murdered Harry Potter star Rob Knox's father has branded his son's killer `spineless scumbag.'

Karl Bishop was given life sentence after he was convicted of the attack on Rob, reports the News of the World.

Rob had been stabbed five times in the chest by Bishop, 22, outside the Metro bar in Sidcup, south east London, in May last year.

Bishop never once showed a sign of remorse, repeatedly laughing and giving thumbs-up signs to pals at the Old Bailey in London.
