I saw that trailer earlier, can't wait for next May to get here.
This movie covers Wolvie's childhood to his time with the Weapon-X program.
2 other characters are also in it, Kestrel, a teleporter played by Will.I.Am, and Silverfox.
Actually, I think it'll only show a small bit of Wolvie's childhood, but the trailer does show him as a kid.
