No, this isn’t photoshopped. Rather, the true story allegedly behind these undeniably similarities is that both the makers of Kindergarten Cop and Silent Hill scouted the same school ahead of production. Cop was filmed there, while Silent Hill went on to use various pieces of the school for their own game.
So yes, Kindergarten Cop does in fact take place in Silent Hill, or vice versa if you prefer that way. I wonder how many more similarities are in there that aren’t pictured above? Someone do some more scouting.
