The Sixth Sense is a 1999 American psychological horror film written and directed by M. Night Shyamalan.

In this tense tale of psychological terror, Dr. Malcolm Crowe (Bruce Willis) is a child psychologist whose new patient has a problem far outside his usual area of expertise. Cole Sear (Haley Joel Osment) is six-years-old and claims to see and talk the spirits of dead people all around him. It seems that Cole has psychic powers and can channel the ghosts of those who were troubled. Cole doesn't understand his powers, and he has little control over them; he's constantly terrified by what he sees, and Dr. Crowe is the only one with whom he feels he can share this secret. However, as the doctor digs deeper into Cole's strange powers, it leads to strange and unexpected consequences for both of them. M. Night Shyamalan, who wrote and directed the film, has a small role as Dr. Hill.

The film had a production budget of approximately $40 million (plus $25 million for prints and advertising). It grossed$26.6 million in its opening weekend and spent five weeks as the No. 1 film at the U.S. box office.

In the United Kingdom, it was given at first a limited release at 9 screens, and entered at No. 8 before climbing up to No. 1 the next week with 430 theatres playing the film.
