Here’s the ChatGPT summation of all the information it’s pulled from its incredibly vast repository of material about this subject, which fully supports the information in my original cite:
Scriptwriters are not typically on the sets of TV and film productions once the script has been finalized and shooting begins. The scriptwriting process usually involves multiple stages, including concept development, writing, revisions, and approval. Once the script is approved and shooting begins, the scriptwriter’s role is often finished, and the responsibility for bringing the script to life falls on the director, actors, and the production team.
However, there are exceptions to this. In some cases, the scriptwriter may be invited to visit the set, especially if they have a close working relationship with the director or production team. They may be consulted for input on specific scenes, dialogue, or character motivations. Additionally, some scriptwriters also work as producers or executive producers on a project, which could involve more involvement in the production process.
In general, though, once a script is in production, the primary creative control shifts to the director and the collaborative efforts of the cast and crew responsible for turning the script into a finished product.
P.S.- Be sure to add a “LOL” to any response you may care to make.
