I loved this film when it first came out. It's a reinvention of the Antonioni film 'Blow Up'. In the original a photographer takes a shot of something he shouldn't have. In this version, John Travolta is a sound engineer for a small-time film company whose microphones 'hear' a sound at the scene of an 'accident'. John Travolta is pretty good in the role and it's an mystery. Nancy Allen doesn't really do it for me, but then she was married to the director (and excelled in some other films). John Lithgow and Dennis Franz are as dependable as ever.
The story is clever and the connection between the beginning and surprise ending very well executed.
A creepy little film, typical Brian de Palma, and it doesn't follow the normal pattern. It is dated, though, which is why I've only given it a 3 star.
