The website productionweekly.com has revealed the working title for 20th Century Fox's Deadpool film, which is "Wham!"
Keep in mind, a working title is used for big budget films all of the time to keep potential onlookers from realizing which film is actually being filmed. As an example, Marvel used the working title "Caged Heat" for Iron Man 3 and "Freezer Burn" for Captain America: The Winter Soldier.
Filming is expected to begin on Deadpool in late March in Vancouver. As of right now, Ryan Reynolds ("Green Lantern") is set to star as the Merc With A Mouth and Tim Miller is set to direct. More cast announcements are expected very soon.
Deadpool arrives in theaters February 12, 2016.
