Following the release of the final Black Widow trailer this morning, which seems to have debunked the fan theory that Rachel Weisz is playing Taskmaster in the movie, the person who people believe is really playing the villain seems to have confirmed that on social media.
When the trailer was released, O-T Fagbenle (who is only officially called “Mason” right now) posted an Instagram post about it and used both the #Mason and #TM hashtags. The Instagram post appears to be deleted, but the Tweet linking to it hasn’t been deleted yet:
Mason is said to be a love interest for Natasha before her days with The Avengers. Making Taskmaster a very personal villain for her as not only will she be fighting all of The Avengers when facing him, it’ll be someone she knows very well from her past behind the mask.
