Rob Knox
British actor (1989–2008)
Robert Arthur Knox (21 August 1989 – 24 May 2008) was an English actor who portrayed the character of Marcus Belby in the film Harry Potter and the Half-Blood Prince, and had signed to appear in its sequel Harry Potter and the Deathly Hallows – Part 1.
Having studied at Beths Grammar School, Bexley, Knox began acting aged 11, gaining small roles in British television shows like The Bill, After You've Gone and Trust Me, I'm a Teenager. His first cinematic appearance was as an extra in King Arthur (2004).
Knox died after being stabbed outside a bar in Sidcup, Southeast London, in May 2008, when he intervened in a fight to protect his brother. His murder attracted widespread attention in the British press, and his assailant, Karl Norman Bishop, was subsequently sentenced to life imprisonment, with a minimum 20-year non-parole period. An annual film festival, the Rob Knox Film Festival, was created in 2008 to commemorate him, by the Rob Knox Foundation which helps fund training for young local people in the arts. The final festival was held in September of 2025.

Why this record matters
“Rob Knox” is worth following because a concise public description often conceals a longer documentary argument. Here, Knox, British and actor provides the most credible route into that argument.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Jul 6, 2026. The linked authority identifier is Q438704. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1989, 2008, 2004 and 2025.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
