After years of easily shredded tanktops and black leather, Deadpool 3 is finally putting Wolverine actor Hugh Jackman in the mutant’s signature blue and yellow costume. Minus the blue underwear–on the outside at least–Wolverine’s big screen costume is a faithful adaptation of the classic spandex that Canada’s finest export has worn in comic books and in animated series over the years. So how did Deadpool 3 director Shawn Levy find the right look for Wolverine? By consulting the “nerdiest nerds” that the Marvel Cinematic Universe had to offer, Levy explained.

Speaking to Entertainment Weekly, Levy said that he and his team went through “multiple, multiple, multiple iterations and fittings” before they settled on the final look for Wolverine. “It also helps that I’m making this movie within the MCU, so I have access to an army of the nerdiest nerds available to a Marvel project,” Levy said.
