Pulse

• Cinematography was by Junichiro Hayashi (also shot Ring and Dark Water), captured on 35mm film with Arriflex cameras — not digital video as sometimes claimed — giving the film its washed-out, sickly color palette.
• Pulse premiered in the Un Certain Regard section at the 2001 Cannes Film Festival, where it won the FIPRESCI (international critics') Prize.
• The film opened in Japan on February 3, 2001, distributed by Toho.
• Dimension Films produced a 2006 American remake starring Kristen Bell, co-written by Jim Sonzero and Wes Craven. It was critically panned (11% on Rotten Tomatoes) but not a box-office bomb, grossing roughly $28-30 million worldwide on a $20.5 million budget.
• The film's dread comes largely from practical, low-tech craft rather than heavy effects work: shadows, grease stains, dial-up modem noise, and strips of red tape sealing doors do most of the horror's heavy lifting.

The ghosts aren't malicious spirits but a psychic overflow: the dead are multiplying faster than the living world can absorb them, and the internet is simply the most recent technology humans built without understanding its metaphysical consequences. The film's apocalypse is an accident, not an invasion.

Every character who dies becomes a red-tape room, a sealed node in a growing network. The internet didn't create the haunting; it just gave loneliness a protocol. The final shot of Tokyo going dark suggests the dead won the bandwidth war.

The two storylines never intersect because they don't need to. Kurosawa is arguing the phenomenon is systemic and impersonal. Nobody is special. Nobody gets chosen. The machine just keeps processing souls.

Tokyo's internet infrastructure cracks open a wound between the living and the dead. Ghosts bleed through dial-up connections and abandoned floppy disks, trapping souls in rooms sealed with red tape. Two parallel stories spiral toward the same void: a plant-shop worker investigates her colleague's sudden suicide and its digital afterlife, while a college student watches his friends vanish one by one into glowing screens. The dead don't want revenge. They want company. And the internet gave them a door that won't close.
