What might not: While the trailer is ominous the end of it borderlines being corny, but hopefully that won't translate into the film. The other concern I have it that the film might be exploitative, but it's hard to tell by this teaser alone.
Random Thought: Emily Browning was Stephanie Meyer's first choice to play Bella in the Twilight movies. Thankfully she turned it down.
When to see it: Australian independent movie debuting at Cannes. Unless it's instant Oscar bait my guess is it's going to take forever and a day to get to my region. Which is unfortunate.
