IMDb is known for being wrong and unreliable most of the time, but according to them Nathan Gamble and Sayed Badreya will in Deadpool. What characters you may ask? Nathan Gamble will be portraying Screaming Child, and Sayed Badreya will be playing Terrorist. Granted, Sayed Badreya is known for playing terrorists in films, but I don't remember there even being terrorists in the Deadpool script that leaked out. Minor characters like Screaming Child or Terrorist are ones that either are announced when filming is occuring or are only revealed in the credits. NOT TWO YEARS BEFORE THE FILM COMES OUT!!
Anyways Deadpool is rumored for a 2012 release date, starring Ryan Reynolds.
