Originally the movie Ouija was going to be huge, in terms of budget, before Universal (the studio releasing the horror feature) balked and almost abandoned the project. The story was tweaked, and it was brought in significantly cheaper, and the rest is history.
It always mystified me why it was originally planned as a big-budget feature (other than the property being owned by Hasbro, the people behind–or should I say culpable–for the Transformers). The movie revolves around a ouija board, a Hasbro product by the way, which are creepy just sitting on a table, never mind interacting with the damned (pardon the pun) thing.
And while I think that Universal not producing Ouija as an expensive feature was a great idea (which should pay dividends at the box office) abandoning Guillermo del Toro’s version of H.P. Lovecraft’s At The Mountains Of Madness wasn’t.
