Hi Murray

Thanks for reaching out in the Lucid community! I recommend browsing our template gallery to see (and use) pre-designed swimlane diagrams. Here are the steps to access the template gallery in case that's helpful for you and others reading this thread. I wasn't able to find a template specifically for film production but there are many options you could modify for your particular use case. I also recommend our Diagram with Swim Lanes article from the help center for more detailed steps on how to work with swimlanes. 

Feel free to follow up here with any additional questions and we're happy to help.
