A movie based on the Deadpool character starring Ryan Reynolds, who played the role in X-Men Origins: Wolverine, is being developed by Fox, according to the Hollywood trades. This is in addition to the Wolverine sequel in development (see “Wolverine Sequel?) and a Magneto film currently planned for 2011.
Reynold’s Deadpool character was featured in one of two special Easter eggs after the credits (see “Two Wolverine Endings”) of Wolverine.
