How did improvisation affect Jean-Luc Godard’s filmmaking methods?

Improvisation was a hallmark of Jean-Luc Godard’s filmmaking, particularly during his early career with the New Wave movement. His approach was characterized by a "drastic nonchalance" that prioritized spontaneity over traditional, scripted production methods.1

The impact of improvisation on his work included:

• Scriptless Production: His debut feature, Breathless (1960), was filmed without a formal script. Godard would sketch dialogue overnight and revise it during or between rehearsals.1
• Directing During Takes: In later films, he sometimes spoke the characters' lines to the actors from behind the camera while the scene was being filmed.1
• Artistic Vision vs. Reality: Godard utilized these improvisatory techniques to observe reality, impose his own creative vision, or interrelate the two, often resulting in a "strangely abstract effect".1
• Reflexive Cinema: These methods helped deconstruct traditional narrative language, contributing to a reflexive style where the filmmaking process itself became a subject of the work.2

By abandoning rigid scripts, Godard maintained an independent, volatile creative process that allowed him to treat his films as intellectual essays rather than conventional narratives.12
