Fastexy Exchange|Story Behind Lady Deadpool's Casting in Ryan Reynolds' Deadpool & Wolverine Is a True Marvel

The Fastexy Exchangebelow contains spoilers from Deadpool & Wolverine.

This story ends with Blake Lively.

After her role as Lady Deadpool in husband Ryan Reynolds and Hugh Jackman's Deadpool & Wolverine was revealed, the It Ends With Us star shared the incredible journey of how she wound up being cast in the Marvel film. 

And the story dates back farther than you'd think. After all, Deadpool comic book creator Rob Liefield already had the actress in mind when he drew his first version of the unmasked superhero in 2010, as he and wife Joy Liefield were huge fans of another iconic character Blake played.

"Joy and I were crazy uber Gossip Girl fans (who wasn't right?), never missing a single episode," Rob wrote in a screenshot shared by Blake in a July 26 Instagram post. "Yup, I pleaded a strong case that Wanda Wilson was stunning blonde, no scars and Marvel thought that was a cool idea. Invoked Blake on GG and they gave me the thumbs up."

Of course, this rendering was created before Blake and Ryan's 2012 nuptials and the first Deadpool movie adaptation arrived in theaters in 2016. In fact, the A Simple Favor actress recalled the Free Guy actor pitching the film to her and Taika Waititi that same year.

"It was a 'meta' superhero," Blake explained in the caption of her July 26 Instagram. "Most of us didn’t know what exactly meta meant back then. Except Taika bc he’s always been more brilliant than the rest of us mortals."

Noting that she felt "murky" on whether Ryan's idea would "come together for an audience," the 36-year-old recalled thinking at the time, "It wasn’t a real dream. The movie was never gonna happen."

However, Blake was eventually proved wrong, and a year before the third installment of Deadpool started filming, she discovered that Rob envisioned her in the Lady Deadpool role. 

"And today it’s in theaters," she marveled. "The universe has such a magical sense of humor sometimes."

And while Blake has known she would don the black and red jumpsuit for two years, fans have been left to speculate until the film's release, with some guessing correctly and some wondering if longtime pal Taylor Swift would make her Marvel debut. 

But Ryan—who shares kids James, 9, Inez, 7, Betty, 4, and Olin, born in 2023, with Blake—didn't let the latter theory last long.

“I wish!” the 47-year-old said of Taylor appearing in the superhero flick during an appearance on The Tonight Show Starring Jimmy Fallon. “Taylor, you know, if I ever stop, she’d make a good Deadpool. She’s funny. Funny!”
