Sorry to break it to you, but Ryan Reynolds isn't doing the full 'Bye Bye Bye' dance in 'Deadpool & Wolverine'

• "Deadpool & Wolverine" opens with a fight sequence set to *NSYNC's "Bye Bye Bye."
• Most of the choreography is performed by a dance double named Nick Pauley, who's credited as Dancepool.
• "If it looks like the person who's dancing doesn't have arthritis, that's him," Reynolds said of Pauley.
