Teen actor Robert Knox, who was fatally stabbed 15-years ago, appeared in Harry Potter after his death.
Knox, from London, had several small TV roles including appearances in The Bill, After You’ve Gone and reality show Trust Me, I’m A Teenager, before landing the role as Marcus Belby in Harry Potter and the Half-Blood Prince.
And, although the character didn’t appear in the seventh book, Knox had also been signed up to reprise his role for Harry Potter and the Deathly Hallows.

However, tragically, Knox never got a chance to see himself star in the movies as just days after filming had wrapped he was stabbed to death on a night out in London.
Knox had been out in Sidcup, east London, in May 2008 when a brawl broke out outside a bar.
The teen intervened in an attempt to protect his younger brother Jamie, then 17, as he was threatened by 22-year-old Karl Bishop, who was armed with two knives.
Bishop stabbed Knox five times. Appearing in court in 2009, he was found guilty and sentenced to life in prison with a minimum sentence of 20 years before parole is considered.

He was also found guilty on four counts of wounding and given an additional three life sentences, to run concurrently.
Speaking during sentencing, Mr Justice Bean said: "I do not think it is proved that you intended to kill Robert Knox. The truth is that you simply could not care less whether you killed him or not.
"Your lack of regret let alone remorse was truly chilling.”

A new documentary, (K)Nox: The Rob Knox Story, is set to released on ITVX on Thursday (23 February) and features interviews with Knox's family, friends and Harry Potter cast members - including Jim Broadbent, Ray Winstone and Tom Felton.
As well as looking at Knox’s heartbreakingly short life, it also aims to highlight the problem with knife crime in the UK and how it remains a ‘prolific issue’ more than a decade on from Knox’s killing.
A synopsis from Q Cumber Films reads: "18-year-old Rob Knox is out celebrating his big break in Harry Potter when he learns that his little brother has been threatened at knife point. He and his friends rush to disarm the man but during the struggle, Rob is stabbed several times and is killed.

"Now his family must try to navigate their grief and anger while under the ever-watchful eye of the invasive British media machine. Meanwhile, more young people than ever are losing their lives on the streets. Something has to be done."
You can watch (K)Nox: The Rob Knox Story on ITVX from Thursday 23 February.
