Finally a movie with the Flash in it. The teaser ain’t that much but it’s to be expected for something that is going to be release in 2016, according to IMDB it will be release in 2016.
While working in his lab during a storm one night, a bolt of lightning strikes a tray of chemicals soaking police scientist Barry Allen with its contents. Now able to move at super-speed, Barry becomes The Flash protecting Central City from the threats it faces.
I think this is part of the introduction to the Justice League where another movie is coming as well, Batman vs Superman and will also be release in 2016.
