Four-time Harry Potter film director David Yates has decided to leave Your Voice in My Head, reportedly due to a family member’s personal health issue.

Deadline reports that Yates wanted to postpone the project, but the writers and producers didn’t want to wait.

Emma Watson is to star in Your Voice in My Head, as we reported in February. No word yet on who will replace Yates. The film is being distributed by Warner Brothers, who has a first look deal with Yates.

Your Voice in My Head is based on the memoir of the same name by author Emma Forrest, who also wrote the film’s script.

Update – David Yates has released a short statement expressing his regret on having to leave the project:

“Unfortunately, due to conflicting schedules and ongoing commitments in the narrow window I was hoping to make this film, it has become no longer possible for me to direct ‘Your Voice in My Head.’ I am sincerely sorry to be leaving such a fantastic project, and I wish producer Alison Owen and everyone involved the very best for what I am sure will be a distinctive film.”‬
