This day ten years ago, Hollywood went into mourning as the news of Heath Ledger's untimely passing made front-page headlines.

The Australian actor was just 28-years-old when he died of a cardiac arrest brought on by an accidental overdose of prescription drugs.

The father-of-one, whose career had gone from strength to strength in the years leading up to his tragic demise, died alone in his Manhattan apartment in the early hours of January 22.

Loved by fans and lauded by critics, the impact the award-winning actor had in just ten short years on the film industry cannot be underestimated, with his final role in The Dark Knight securing him an Oscar, which was awarded posthumously.

Today, film fans and industry insiders take to Twitter to honour the actor who brought us numerous memorable characters including Patrick Verona. Ned Kelly, Ennis Del Mar and The Joker.
