Tom Felton has signed on as a series regular for superhero series The Flash.

The Harry Potter star is trading in the wizarding world for the DC Comics universe in the upcoming third season of the TV drama.

Felton will play the role of Julian Dorn, a crime scene investigator who works with Barry Allen, aka The Flash, at Central City Police Department, but suspects there's more to his co-worker's good guy reputation.

The British star last appeared on TV in anthology drama Murder in the First, as well as Full Circle and the historical miniseries Labyrinth.

Felton will make his debut on the The Flash when the series returns to TV this autumn (16).
