I saw the trailer of a movie once, and I really wanted to see it; too bad I can't remember the movie title. Help me out? I'll decribe the trailer.
There is a brunette man and a blond woman with a short haircut, they're married. They are in a city park with their dog, I think I recall that it is a german shepard. They are playing fetch, and the tennis ball that the man throws goes into a tunnel kinda far away. They wait for the dog to come back, but soon hear the dog whine, then bark, but is quickly silenced. The man goes in after the dog, but never comes out. There was two african american men who took the dog and killed the man. Meanwhile, the woman is devastated from the loss of her husband and her beloved pet. Though, she's hardened now, and carries a pistol in fear of another encounter like that again.
Coincidentally, the two men encounter her again, in a dimly lit subway station. They are all alone, and the taller one takes out a curved, serrated nine inch blade and places it right above her left ear, slowly moving it but not yet making a move to chop it off. XP He mutters under his breath,"...like taking candy from a baby...." Suddenly, the woman takes out the gun, shoves the cold metal tip of the pistol hard against his stomach, (I think she mutters,"not again", but i'm not sure) and shoots him. The other man gets away, though.
Later, she confronts the other man on purpose. It's in the pitch black of night, and he talks to her behind a tall, wrought iron fence, holding her dog on a leash, torturing her to see the sight of her dog in someone else's hands. She shoots him, and takes back her dog. The trailer ends.
So, any ideas on what the movie is called????
