Tak jak w temacie. Jak ktos nie widzial a jest ciekaw to tutaj streszczenie trzech róznych
zakonczen.

There are three endings; the theatrical ending, the original 2007 ending and the
"Unrated" ending.

The theatrical ending (suggested by director Steven Spielberg) has Katie awaken to
once again stare at a sleeping Micah for several hours. She then goes downstairs into
complete darkness and suddenly starts screaming for no apparent reason. Micah hears
her and wakes up, running to her aid. The camera can only see the bedroom and dark
hallway as it records what sounds like a struggle between Micah, Katie and whatever
else is downstairs with them. Micah and Katie's screams suddenly stop, and the brief
silence is followed by the sound of heavy footsteps coming up the stairs. Micah's body is
suddenly hurled at the camera, knocking it over. Katie appears in the doorway, her
clothing covered in blood. She crouches down and starts sniffing at Micah's lifeless
body, then smiles at the camera before lunging toward it and the screen smash cuts to
black and the credits roll.

In the original 2007 ending, Katie returns to the bedroom after the struggle heard
downstairs, wielding a knife with blood on her tank top. She then sits next to the bed and
rocks back and forth in a catatonic state throughout the remainder of the following day.
Her friend Amber calls the house, and later arrives, discovering Micah's body
downstairs. When police officers arrive, Katie comes out of her catatonic state and
approaches them asking for Micah. The officers instruct her to drop the knife, but shoot
her after being startled by a door suddenly slamming behind them. The movie ends with
audio of the police discovering the camera as the credits roll.

The Unrated DVD/Blu-ray has an all-new ending (that was, apparently, shown once
before at a film festival) which involves Katie returning to the bedroom with the knife (just
like she did in the unrated ending) and slitting her own throat in view of the camera. The
credits then roll.
