Percy Jackson & the Olympians: The Lightning Thief (2010)*

Gabe walks into the apartment where we see all his stuff is boxed up.  He then goes to the refridgerator which is locked and has a sign on it that says to not open.  He breaks the lock, opens the door and we then see the head of Medusa.  The screen goes black as we hear the sound of Gabe turning to stone.
