Lenny Rush is keeping the technical details of his Dobby performance secret, but the young actor says fans should be excited about how the beloved house-elf will look in HBO’s Harry Potter television adaptation.
Rush has been cast as Dobby for the second season of the series, which will adapt Harry Potter and the Chamber of Secrets. Asked whether the character will be created with makeup, motion capture or voice performance, the actor declined to reveal the production’s approach.
Rush says he is pleased with Dobby
The 17-year-old said he has seen the direction the production plans to take and is very pleased with the character’s appearance. He also emphasized that he is excited to join the project while avoiding spoilers about how Dobby will be brought to life.
Dobby is one of the most recognizable non-human characters in the Harry Potter universe, making the visual interpretation a closely watched part of HBO’s long-form adaptation.
Season two expands the wizarding world
The second season is expected to broaden the world established in the first installment by introducing major characters and story elements from Chamber of Secrets. Rush’s casting gives the reboot a new performer in a role closely associated with the film franchise.
For now, the actor is promising a Dobby he believes fans will be happy to see.
