- Handcrafting vs. 3D printing: Props like the Triwizard Cup were handcrafted, while others such as Spectrespecs were 3D printed for uniformity across takes. Both methods allowed the team to achieve high detail, durability and repeatable results for scenes involving stunts or multiple copies.
- Real vs. fake materials: While some props used genuine materials, like real metal for goblets or glass for potion jars, others used fakes for practicality purposes. Food was often wax, and heavy-looking books were actually foam-filled to lighten actors’ load during long shoots.
- Research behind authentic magical objects: Designers researched Victorian gadgets, Celtic symbols and antique weaponry to inspire magical object designs. The goal was to make props feel like plausible artefacts from a centuries-old wizarding world.
