Ryan Reynolds and Hugh Jackman react as Deadpool and Wolverine tops global box office

Ryan Reynolds admitted it's "kind of hard to process" after 'Deadpool and Wolverine' made a whopping $438 million globally during its opening weekend.

The R-rated Marvel blockbuster is now the eighth biggest domestic opening movie of all time after making $220 million in North America alone.

Reacting on his Instagram Story, Deadpool actor Ryan, 47, wrote: "This is kind of hard to process.

"But thank you to everyone who went to see the film this weekend... wow."

Hugh Jackman (Wolverine), 55, wrote: "Deadpool and Wolverine is the #1 movie in the world. Thank you ALL."

Ryan recently divulged that he changed the title of ‘Deadpool and Wolverine’ because Internet leakers “hated” the Shawn Levy flick's original name.

He chose to change the name in February after online sleuths went ballistic after learning the film was called ‘Deadpool and Friend’.

During an appearance on ‘Jimmy Kimmel Live!’ - on which the movie's stars filled in as guest co-hosts - He explained: “I’ve never told this story anywhere, but the movie was originally called ‘Deadpool and Friend’. I am actually not joking.

“On the eve of the Super Bowl, the Super Bowl is where we first launched the trailer for Deadpool — not Friend, but Wolverine — it leaked because of the internet.

“The title leaked. We looked at it and listened, and they hated that title. We were not feeling so good about that anymore.”

Although he was adamant to amend the flick’s name, Ryan admitted it took a while to convince Marvel Studios to agree to the change.

He said: “We were like, ‘No, we’re changing the title, I will never call this movie ‘Deadpool and Friend’. And they did it, they did it. They really changed the title.”

Even before the name leaked, he was determined to ensure more sensitive details about the movie didn’t make its way online before hitting cinemas, and so planned to film a fake “intentionally bad” film known as ‘Alpha Cop’ to throw leakers off the scent.

He explained to Hugh during a stint on ‘Hot Ones’: “The original idea with this movie to shoot a fake movie called ‘Alpha Cop’ that was intentionally bad.

"I even had one of the posters made — it was about two guys who are sharing one brain and together they make the ultimate cop. And the poster says, ‘Alpha Cop: Two Cops, One Brain. All Balls.’

“It was meant to be kind of like horrible, so 10 people in America would go see this movie on opening weekend and five minutes into the movie, the Marvel logo would flip up and it would actually be ‘Deadpool and Wolverine’.”
