The Kovak Box is a 2006 psychological thriller film directed by Daniel Monzón and starring Timothy Hutton, Lucía Jiménez, Annette Badland and David Kelly.

On the island city of Palma de Mallorca, David Norton (Hutton) promotes his latest book, The Kovak Box before a small private gathering of European fans.

While nothing unusual happens, one of the audience members has a distinctive Russian Mafia arm tattoo, and the hotel concierges are subtly condescending towards Norton, despite the writer's mannered patronage and celebrity status.

Norton finds that the events coincide with the plot of his latest book, which is based on a real individual: Frank Kovak (Kelly), a Hungarian doctor who was disgraced and driven to exile after his experiments were passed off as psychological warfare.

Kovak used neural implants and paid a network of criminals to reproduce the experiment—in which everyone takes their life (or suffers a brutal death) while the Gloomy Sunday song plays—on Norton.
