Check out video from Steven Merchant's Instagram of the actor getting his head shaved for Wolverine 3.
"An actor prepares," Merchant added to the post.
It's unknown what character Stephen Merchant is playing for The Wolverine 3, but it has been said the Reavers may be featured.
Perhaps he's playing Bonebreaker?
The untitled Wolverine 3 has a March 3, 2017 release directed by James Magold starring Hugh Jackman, Patrick Stewart, Richard E. Grant, Boyd Holbrook, Elise Neal and Eriq La Salle.
