Final Approved Script
The locked version of a screenplay that production is based upon.
Definition
The final approved script is the locked version of a screenplay that production budgeting and planning are based upon. Once approved, changes are carefully controlled and tracked using a revision color system, as modifications can impact budget, schedule, and commitments.
Script lock is a critical production milestone. Prior to lock, creative development continues; after lock, the focus shifts to execution. Significant post-lock changes require formal approval and budget reassessment.
Why It Matters
Production planning depends on a stable script. Understanding script lock helps all stakeholders know when the creative phase ends and execution begins.
For production teams, script discipline after lock prevents the costly chaos of continual changes.
Examples in Practice
The final approved script triggers detailed budgeting, as production can now plan for exactly what needs to be shot.
Post-lock script changes are tracked in pink, blue, and yellow revision pages so everyone knows what's changed.
A significant rewrite after lock forces schedule and budget revisions, delaying the production start.
