Despite its twists and turns, the film has had a happy ending, becoming the biggest grossing R-rated film of all time in the North American market.

Interestingly, ping-pong, which is currently captivating Chinese audiences watching the Paris Olympics, has been part of the process.

As Jackman and Reynolds refined their comedic chemistry with director Levy, they played each other on a ping-pong table sent to the set by Reynolds' wife, actress Blake Lively, according to the American magazine Vanity Fair.

Reynolds said that he and his wife have photos of famous Hollywood duos playing ping-pong. Memorable moments include Henry Fonda and Jimmy Stewart playing a game in 1937, as well as Paul Newman and Robert Redford enjoying a match in 1968, during a break in filming Butch Cassidy and the Sundance Kid.

Levy, who attended the Shanghai event with the two actors, describes playing ping-pong as a metaphor for the movie.

He elaborates by saying that the dynamic between Wolverine and Deadpool in the film mirrors the essence of ping-pong, involving both competitive back-and-forth exchanges and moments of collaborative teamwork.

"The story develops into a tale of friendship. It's an emotional aspect of Logan that we haven't seen in other movies. It's what makes Deadpool& Wolverine so exciting for fans," says Levy.
