Every scene was filmed in ten-minute uninterrupted takes. The directors would hold up signs reading "Keep it up" or "Boring" for the actors and actresses instead of stopping the filming.

Filmed in just five days, using the same set and much of the same cast as Smoke (1995). The premise of the film came to directors Wayne Wang and Paul Auster while watching an improvisation session between Harvey Keitel and others to help them get into character for filming Smoke (1995). They decided that the improvisations were so funny, that they would spend a few days after shooting Smoke (1995), just filming a film that is almost entirely improvised. Auster and Wang claim to have "borrowed" the idea of shooting another movie on the back of an existing one from Roger Corman, who often used to shoot movies very quickly on leftover sets from other productions.

The scene with Giancarlo Esposito, Stephen Gevedon, José Zúñiga, and Malik Yoba took all day to film. The extremely hot temperature, combined with the lack of a script, made it difficult for the actors and actresses to improvise a good scene. After many takes, Harvey Keitel secretly told Peggy Gormley to slap Gevedon in the scene to garner an energetic reaction. That take is used in the film. But the long day took a toll on Director Wayne Wang, who was suffering from bronchitis, so Paul Auster stepped in as director for the next two days.

Jim Jarmusch's scene was originally intended for William Hurt, who was to reprise his role from Smoke (1995). But Hurt was unavailable.

Mel Gorham's performance of "Fever" was filmed three months after the film wrapped. At the film's wrap party, Gorham performed a rendition of "Fever" that so impressed the film's producers, they decided to add a scene with her performing the song.
