Before Robert Downey Jr.’s return to Marvel as Doctor Doom, the Deadpool & Wolverine team considered bringing him back as Tony Stark. A scene featuring Downey as Stark was written but ultimately not included in the final movie. The scene in the finished film shows Wade Wilson visiting Avengers Tower in 2018 to meet with Happy Hogan, played by Jon Favreau, to join The Avengers, but he is rejected.
Despite the absence of Downey, the film has been a success at the box office, expected to cross the $1 billion mark. The writers, who spent years developing the Deadpool universe, reflected on the challenges and successes of the latest movie.
When Hugh Jackman expressed interest in returning as Wolverine, it influenced the direction of the script. Jackman's involvement led to a focus on a road trip theme and the introduction of new elements like the concept of an anchor being, inspired by Marvel canon.
Returning actors like Channing Tatum, who portrayed Gambit, provided input on their characters. Tatum's accent choice for Gambit influenced the script, adding a comedic element to the character's interactions with Deadpool.
The writers acknowledged the importance of balancing humor with respect for the Marvel Universe. They highlighted that while they make fun of various aspects, they also recognize the achievements of Marvel and its impact on the film industry.
Despite considering a cameo by Downey as Tony Stark, the writers ultimately decided not to include it in the film. The decision was influenced by Downey's future role as Doctor Doom in the Marvel Cinematic Universe.
