X-Men Origins Wolverine
(May 1, 2009)
You could find the hatch from lost but it is well hidden behind some wood
hidden in the trees you find a cave and next to a skeleton with a yellow exclamation point on his head like in WoW is The Lich King's sword from World of Warcraft
there is a teleport machine you go inside of to find a cake with the message "SURPRISE!" all over the wall and floor
Marvel didn't have any right to use LOST,Warcraft, and Portal, but they only included a minor references.
