Krishnan Nair (25 July 1939 - 16 November 1980), better known by his stage name Jayan, was an Indian film actor, naval officer, stunt performer and cultural icon of the 1970s. He starred in over 120 Malayalam films. During his film career, he was primarily an action star and was particularly famous for his macho image and unique style. He was reputed for his chauvinistic appeal and well known for performing stunts of a dangerous nature on his own.

On 16 November 1980, Jayan was killed in an accident on the set of the movie Kolilakkam (English: Shockwave). The climactic scene of the movie was being filmed in Sholavaram, near Madras, Tamil Nadu. Jayan always performed his own stunts, and for this movie he was performing a particularly dangerous stunt that involved him boarding an airborne helicopter from a moving motorbike. The shot was accepted by the director in the first take; altogether three shots were filmed.  According to the film's production executive, Jayan insisted on yet another re-take as he was not satisfied with its perfection. During the re-take, the helicopter lost its balance and crashed along with Jayan who was hanging onto the landing skids, and he later succumbed to his injuries.  After his death was confirmed, a slide was added during the theatre show of his movie Deepam, which was running in packed houses, informing his death to the viewers who witnessed it with absolute shock and disbelief. A large number of his fans burst into tears and ran out of the buildings, while many continued to watch the movie, refusing to believe it and taking it for an ingenious promotion for some upcoming project.  Jayan's body was taken to Trivandrum via aeroplane and later it was taken to his home in Quilon, where he was cremated. Thousands paid homage to the late actor, and the police had to take huge measures to deal with the crowds. His mother Bharathiyamma became bedridden after this incident, and she too died two years later.  Some conspiracy theories emerged regarding the circumstances of his death, primarily because the pilot and his co-star Balan K. Nair, who was in the helicopter, survived with minor or no injuries. Nevertheless, it has been confirmed as a genuine accident.
