Which activity does NOT occur during the pre-production stage?

During the pre-production stage, several crucial activities lay the groundwork for the film's eventual production. Shooting the film is not one of those activities, as it takes place during the production stage. The pre-production phase focuses on meticulous planning, organizing resources, and preparing everything needed to facilitate a smooth filming process later on.

Budget planning is essential to ensure that the project has the financial resources it needs. Casting actors involves selecting the appropriate talent to bring the characters to life, and creating storyboards is vital for visualizing scenes and planning the shots. All these activities are integral to pre-production, while actual filming occurs after that phase has been completed.
