We get our first look at Jennifer Lawrence in the form of a leaked image from recently screened footage of X-Men: Days Of Future Past.
Bryan Singer attended the Fantasia International Film Festival where he presented footage from the movie.
The footage featured a Wolverine with grey hair from the future with Iceman sporting a goat-tee, Kitty Pryde and a sad Rogue. Prof. X and Magneto are confincing Logan to travel back into the past to talk to Charles Xavier from the 70s. Bishop, Blink and Warpath are shown as members of the resistance.
McAvoy is shown with Cerebro, with Fassbender holding a gun. Mystique transforms into a soldier, and there are shots of Bolivar Trask (Peter Dinklage) testifying before Congress. Logan is shown confronting McAvoy, and the footage ends with both Xaviers face to face.
Sounds pretty much like the Comic-Con footage.
You can read more about the footage description from 24panelspersecond.
