X-Men: First Class: Movie Set Images - Oliver Platt, more
These are from twitter user MuscleNerd.
The first image looks like the aftermath of a mutant battle, or perhaps a mutant that couldn't control their power, as we see the military in the background and a cement slab thrown(?) on top of a vehicle.
The second features what looks to be Jennifer Lawrence who plays Mystique, Charles McAvoy (Charles Xavier/Prof. X), Oliver Platt as "The Man In Black" and Rose Byrne (Dr. Moira MacTaggert).
