David Prior has clearly been waiting too long to be recognized by the world for his unmistakable ability and if anything David Fincher has downplayed just how talented the man is.  AM1200 is an incredibly atmospheric, suspenseful and intimidating horror with intelligence and to top it all off looks beautiful and does all of this in under an hour.  It’s only fault is it’s not three times longer.

Prior has done more with 40 minutes than most seasoned genre directors can accomplish with 90. The film is unsettling from frame one, and gradually builds upon this growing sense of unease as its narrative transports our hero from the big city to the far reaches of absolutely nowhere. Prior's ability to generate suspense, as well as his loving, well-executed nods to Lovecraftian horror, is beyond impressive. Sam's descent into the AM1200 offices is one of the most unexpectedly unnerving sequences I've encountered in recent memory. What's more, the film's gory finale is top notch, and only adds to the feature's spooky aesthetic.

Well made and genuinely squirm-inducing...

-- Douglas Perry, The Oregonian

A taut protagonist-on-the-run thriller that devilishly morphs into an atmospheric, razor-sharp tale of supernatural terror under your very nose.

Director David Prior packs quite a wallop in this long short. He plays with the standard horror film ploys, only to deliver no stereotypical payoff. This allows the film's main character to behave in a believable fashion, while ratcheting up the tension and building anticipation for the scares to come.  This is one film you need to see with the lights off.

An exquisite film with lush production, beautiful photography, sharply minimalist writing and incredible performances that focuses on creepy rather than jump-out-and-go-boo. This is a movie to which the term horror most definitely applies.  It was the last thing I thought about last night and the first thing I thought about this morning.

David Prior, who was the writer, producer and director, creates an atmosphere of foreboding and dread that I haven’t experienced in a film since The Woman in Black. In fact, he does so more effectively...

AM 1200 is one of my favorites so far this year.

The tension is built up slowly and maintained, fully gripping the viewer, making for fantastic, and horrifying, escapism... the most terrifying cinematic experience I've had in a long time.

Prior effectively builds a mood of dread and keeps it up throughout the forty minutes of runtime, which is exactly as it should be in this type of film
