Bryan Singer Confirms Mister Sinister as Villain in 'Wolverine 3'
As we wait for more news on the third and final Wolverine film starring Hugh Jackman, Bryan Singer has confirmed via the audio commentary for X-Men: Apocalypse that Nathaniel Essex will be a villain in the film.
Nathaniel also goes by the name of Mister Sinister, a villain capable of terrible things and considered as large a villain as anybody perhaps save for Apocalypse. In the post credits scene for Apocalypse, a brief case can be seen bearing the name 'Essex Corp.'
The film will be Patrick Stewart's final turn as Professor X, leaving the role exclusively to James McAvoy.
