That's true, they really wouldn't have to say anything about WHY he is green. I just really like the Morlocks and would like a mention of them at least; and the first thing I thought of when I saw Leech had been cast was the Morlocks. Storm vs. Callisto would be fantastic - it should be a knife fight for the leadership of the Morlocks. Well, I guess it wouldn't have to be, but those were some classic issues. Frankly the X-Men comics have enough material for 20 movies at least. Especially when you factor in all the X-Factor, X-Force, New Mutants, Generation X, Excalibur, Age of Apocalypse, etc.
