Please help me name this movie.
Ok so I remember a while back (a year ago I believe) seeing a trailer for a new movie that was coming out about an office worker who has reached his limit and decides to bring a gun to his work. While having the gun in his desk another employee walks in and opens fire with a gun of his own. The first guy then uses his gun (which he was going to shoot up the office with) to save the rest of the work place.
Do any of you happen to know what this movie was called?
I searched it on google and a few other sites but was unable to find it.
Thanks
