Disney’s Star Wars has cast its first transgender actor in a major role, hiring British male-to-female YouTube personality Abigail Thorn for the role in the upcoming Disney+ series The Acolyte, according to multiple reports.

Abigail Thorn is reportedly set to play a character named Ensign Eurus in the series, which is expected to begin streaming sometime next year. The Acolyte reportedly takes place during the High Republic period, which is set before the events of the Star Wars movies.

The series has already cast “non-binary” actress Amanda Steinberg in its lead role.
