Filming on the second season of HBO’s forthcoming Harry Potter series appears to have started earlier than expected, according to cast member Asha Soetan. The early progress matters because HBO and Warner Bros. Discovery are reportedly planning overlapping production to reduce gaps between seasons as the young cast ages.

Soetan, who plays Angelina Johnson, said she had returned to set for confidential scenes, though HBO has not formally confirmed production has begun. Season 2 is expected to adapt Harry Potter and the Chamber of Secrets, with Jon Brown joining Francesca Gardiner as co-showrunner; the article also reports that Kit Harington will play Gilderoy Lockhart.
