HBO has announced the actors who will portray Tom Riddle, Dobby and Ginny Weasley in the second season of its new “Harry Potter” series.

In a post on its social media account, HBO announced that British actor Billy Barratt will portray Tom Riddle, the younger version of Lord Voldemort. Lenny Rush will appear as Dobby, the house-elf, while Bonnie Hill will portray Ginny Weasley, Ron Weasley’s sister. Hill has joined the cast for the role, replacing Gracie Cochrane, who was initially cast for the first season.

At the age of 13, Barratt became the youngest person to win an International Emmy Award for Best Performance by an Actor for his role in the film “Responsible Child.”

Rush is known for his performance in the series “Am I Being Unreasonable?” The British actor won the BAFTA Television Award for Male Comedy Performance for the role.

It was previously announced that Nicholas Hoult was set to portray Gilderoy Lockhart in the second season. However, it was later announced that the role had been given to Kit Harington due to Hoult’s busy schedule.
