How to Improvise an Entire Show - Interview with Curb Your Enthusiasm Writer/Director Jeff Schaffer

Seinfeld writer and Curb Your Enthusiasm director Jeff Schaffer joins The Screenplayed Breakdown for an in-depth discussion of how one of television’s most influential comedies is actually made. Drawing on three decades of collaboration with Larry David, Schaffer explains why Curb is built without a traditional script, how stories are constructed through outlines rather than dialogue, and why Larry David actively avoids rehearsal to preserve genuine surprise on set. The conversation traces Schaffer’s career from Seinfeld to Curb, highlighting how both shows rely on rigorous structure beneath an appearance of chaos.

Schaffer also details the practical realities of directing improvisation: live-directing actors, moving cameras mid-scene, feeding lines during takes, and shaping episodes simultaneously as writer, director, and editor. He describes Curb as being written three times — in outline, on the day of shooting, and again in the edit — and explains why some of the show’s most iconic moments emerge unexpectedly in the moment. The episode offers a rare, craft-focused look at improvisation at the highest level of television, aimed at film fans, television audiences, and anyone interested in how great comedy is actually made.
