I checked the Days of future past wiki page and while It can be edited by anyone there Is Intresting rumor there.Lucas Till Is listed In cast.
Now Peter Dinklage,Omar Sy,Booboo Stewart,and Adan Cato are all listed as
to be announced characters.
It should be noted than unlike Rose Byrne,January Jones,Jason Flemyng,and
Caleb Laundry Jones he never siad he wouldn't be back for DOFP.
At least wiki Is better than Internet movie database edit which has Peter rumored as Puck
