It’s been a while since we learned that Richard E. Grant would be appearing in the final installment of the Hugh Jackman/Wolverine franchise, simply titled Logan. That news was first revealed way back in April. However, it’s taken until now for a confirmation of exactly which character Grant would be playing.

Many fans, including us, speculated that Grant was going to be playing Mister Sinister when word leaked out that he would given a “mad scientist” role. But a fresh Instagram post from the film’s official account gave us the ultimate clue today.

The “Rice” that the post refers to is actually Dr. Zander Rice. In the comics, Dr. Rice is part of the team that revived the Weapon X program and helps create X-23 (aka Laura Kinney, a female child clone of Wolverine with similar abilities). We’ll have to wait and see what kind of influence he has in the movie.

Logan, which stars Grant, Jackman, Patrick Stewart, and Dafne Keen as Laura, hits theaters March 3, 2017.
