Deadpool writers Paul Wernick and Rhett Reese hope Merc with a Mouth will continue to live in the R-rated universe they created as well as a possible crossover with the Marvel Cinematic Universe (MCU). The writer duo, who are in for the potential third sequel with Ryan Reynolds returning as the titular antihero, said the project is still up in the air.

"The plan and the hope is that Marvel allows us to continue Deadpool in his R-rated universe that he lives in and also, hopefully over time, we get to play a little bit in the MCU sandbox as well," Wernick told io9 website. Reese added it is "all undetermined" for now as they are finding out the right entry point for the character.
