Hi there, Tom! Thanks for reaching out and for considering the PRO plugin. We hope you choose it. 🙂
Great question. You can certainly add any of the Event widgets (Event List, Event Calendar, etc.) to any number of widgetized areas that are set up on your site and configure them per use.
I think the tricky part in your case will be creating a unique widgetized area for each film. As long as each film has its own widgetized area registered, I think this will work for you. Here is the direct link to the WordPress Codex for creating Widget Areas.
By default, the Events List widget allows you to filter events by Category and Tags to control what gets displayed in the widget (screenshot). You can add as many of these filters as you want on a per-use basis to fine tune it to your needs for each film. For your specific case, I would add a category or tag for each event tied to film so you can filter them as needed.
Does this help answer your question? Please let me know. 🙂
Cheers!
Geoff
