Re: 'X-men: DOFP' Official CAST Thread (announcements and discussion)
First of, from what Singer has said, he's not shoehorning anyone in. If you have a plot purpose, you're there. If you're not, you're not.
Two, Leech was terrible.
Three, his powers are of absolutely no use in this plot.
Four, ain't no general public clamouring for the return of Leech.
And finally, the grand return of Wolverine, Storm, Rogue, Iceman, Shadowcat, Colossus... and Leech. One of these things does not belong.
