The Remake
They should remake this with Jake Gyllenhaal & Scarlett Johansson in the leads with Paul Bettany as the husband and Keifer Sutherland as the detective.
It should be rewritten slightly so that the ghost bits at the end are more scarier and darker, as I found them a bit boring. And BinJip should escape from Prison using his newly discovered mutant powers.
The pace should be quickened cos at times the film dragged.
