Mister Frost is a 1990 supernatural thriller film starring Jeff Goldblum and directed by French filmmaker Philippe Setbon, who also co-wrote the screenplay with Derry Hall, Brad Lynch and Louise Vincent.
After not speaking for two years after his arrest, Frost's long silence is broken when he encounters Sarah Day, a doctor at the asylum.
Day naturally does not accept this, but strange things begin to happen around her and Frost demonstrates on multiple occasions feats that would be difficult to dismiss as simple sleight of hand.
The turning point for Day comes when her brother, after being confined to a wheelchair for most of his life, suddenly regains use of his legs.
Gradually, Day is convinced that Frost is telling the truth and, to spare others from harm, agrees to kill him.
