Reynolds announced the news by posting an image Thursday of the Deadpool character on his Twitter account.
“It’s chimichanga time” is a reference to Deadpool’s favorite food. Mike Oncley created the rendition of the character’s head made up of spent bullet cartridges.
Fox announced several months ago that it had slotted “Deadpool” for Feb. 12, 2016. Reynolds, who portrayed the character in 2009’s “X-Men Origins: Wolverine,” has been expected to star for many years.
Tim Miller is directing the superhero film from a script by Rhett Reese and Paul Wernick. Lauren Shuler Donner is producing.
The talkative mercenary character, also known as Wade Wilson, was created by artist and writer Rob Liefeld and co-writer Fabian Nicieza. He first appeared in print in 1991.
Deadpool’s primary power is the ability to heal quickly.
With Reynolds reprising his role in the film, it will mark his first superhero project since “Green Lantern,” which floundered at the box office in 2011.
Reynolds is repped by WME.
