HBO’s upcoming Harry Potter series announces new castings for season 2, which will adapt elements from “Harry Potter and the Chamber of Secrets.” The production fills the roles of Dobby the house-elf and Tom Riddle, also known as young Voldemort, along with a new actor for Ginny Weasley.

Across multiple outlets, the same three casting decisions are reported: Lenny Rush is set to play Dobby, Billy Barratt is set to play Tom Riddle/young Voldemort, and Bonnie Hill is set to play Ginny Weasley. Polygon and other outlets frame the changes as part of the “Chamber of Secrets” storyline progression.

One point of emphasis varies by outlet. Deadline notes Barratt’s recent accolades and that Ginny is being recast, while Variety also identifies that Hill replaces a prior actor for Ginny. Together, the coverage indicates these are additional major characters added or refreshed ahead of season 2, with details focused on which roles are recast and who is cast for each part.
