'The Apparition' trailer summons ghost of the Philip Experiment

The new trailer for Aug. 24 film The Apparition centers around a group of young researchers who set out to create a supernatural entity. Starring Tom Felton (Malfoy from the Harry Potter flicks), Sebastian Stan (Bucky from Captain America: The First Avenger), Ashley Greene (Alice from the Twilight movies), the trio postulate that ghosts only exist because humans believe in them - and that those beliefs and thoughts can actually create thought-form "hauntings."

Based on what we see in the short clip, the film doesn't look very original. With the tagline, "Once you believe, you die," there seems to be a lot of leaning on The Ring, The Grudge (good to see the Yurei is still getting jobs) and Paranormal Activity. And there's a weird paranormal fungus that looks kind of out of place - and is it threatening New York City and the world, as well?

But what makes The Apparition interesting is that it looks to be (very) loosely based on a true story, which we'll explore after the jump...
