Broadcast Release of “(K)nox: The Rob Knox Story” Announced

(K)nox: The Rob Knox Story is a documentary honoring the life of Rob Knox, who starred as Marcus Belby in Harry Potter and the Half-Blood Prince. Knox was tragically murdered after being stabbed multiple times while attempting to save his younger brother in 2008, just days after his filming for Half-Blood Prince ended. He was 18 years old at the time of his death and never saw the film’s release. The documentary is finally being broadcast on television for audiences in Germany in late December and in the United Kingdom in 2023.

Focusing on the life of Rob Knox, the feature-length documentary gives viewers an idea of what Knox was like as a person and an actor, with behind-the-scenes footage from the set of Half-Blood Prince and interviews with Knox’s family and friends, fellow Potter actors Jim Broadbent (Horace Slughorn) and Tom Felton (Draco Malfoy), and David Yates, the director of the final four Harry Potter movies and the Fantastic Beasts films.



The film was named Best Feature Documentary by the London Independent Film Festival and subsequently premiered at the festival in April 2021. In November 2021, it was announced that Woodcut International had signed on to be its worldwide television distributor, with Koulla Anastasi executive producing it.

In a statement at the time, Anastasi commented on the film’s importance in helping raise and tackle issues with knife crime.

This film pays homage to a young man whose legacy has shone a light on knife crime, and his fame in the Harry Potter movie has created a unique vehicle to draw attention to the soul[-]destroying impact crimes of this nature have on so many lives.

The European premiere will take place on December 29 on Germany’s Sky Crime. Coinciding with the German release, the documentary’s soundtrack by Taxi Joe will be released on all music streaming platforms on December 29 as well. (K)nox: The Rob Knox Story will be broadcast to viewers in the UK on February 23, 2023, on ITV.
