Harry Potter star Domhnall Gleeson recently opened up about his first day on the set of Harry Potter and the Deathly Hallows Part 1, where he fumbled his accent so badly that he referred to it as “one of the worst days of [his] life.” Here’s what went wrong with Domhnall Gleeson in Harry Potter and the Deathly Hallows Part 1.

One of the stars of the Harry Potter film series had a terrible first day on set when his first take went horribly wrong.

There wasn’t a spell in the world that could’ve helped Domhnall Gleeson on his first day on the Harry Potter set. The Irish actor, who starred as the eldest Weasley brother Bill in the film series, explained during a recent visit to Late Night that his attempts to pull off his character’s English accent went completely off the rails during his first few scenes.
