""The film nicely tees [Deadpool] off for his own spin-off film," said Katz, who raved about Ryan Reynolds‘ portrayal of the wise-cracking mercenary. In Marvel’s comic book universe, Wade Wilson (a.k.a. Deadpool) is a product of the same “Weapon X” experiments that Wolverine was subjected to by the Canadian government, but the experiments left him disfigured and mentally unstable."
This is still only rumor at this point, and Fox has not confirmed any plans to make a Deadpool movie. [SOURCE]
