To create the Diagon Alley set, filmmakers used a variety of techniques:
1. Real-World Construction: A massive set of Diagon Alley was built on the Warner Bros. Studios Leavesden lot in England. This involved:
* Detailed Construction: Building actual shops, stores, and buildings with intricate details, including cobbled streets, ornate signage, and working windows.
* Props and Set Dressing: Creating thousands of props, such as magical items, books, and food, to fill the shops and streets.
* Special Effects: Incorporating special effects like moving props, animatronics, and visual effects to bring the magical aspects of Diagon Alley to life.
2. Computer Generated Imagery (CGI): While the real-world set was extensive, CGI was used to:
* Enhance Realism: Add visual effects to the set, such as smoke, magic effects, and crowd scenes.
* Extend the Set: Create parts of the set that were too difficult or impossible to construct physically, like the exterior of Gringotts Bank.
* Create Special Effects: Incorporate CGI creatures, magical effects, and environmental elements that would have been impractical or impossible in the real world.
3. Behind-the-Scenes Filming: The documentary captured the process of building the set, including interviews with the set designers, artists, and special effects experts. They filmed various aspects of the production, such as:
* Construction Process: Showcasing the construction of the set, from the initial planning to the final details.
* Prop Creation: Highlighting the creation of unique props and set dressings.
* Special Effects: Demonstrating the use of practical and digital effects to enhance the magical elements.
* Interviews: Featuring interviews with cast and crew members, discussing their experiences and insights.
