Harry Potter and the Philosopher's Stone

Or Harry Potter and the Sorceror's Stone if you saw it in the States. This was the first Harry Potter book and, consequently, also the first film. We made the trim on top of the Restricted section of Hogwarts Library into which Harry, Hermione and Ron sneak under cover of the Invisibility Cloak.

Gringotts

We were also asked to make the detail around the mirrored windows in Gringotts Bank, seen in the background of the shot here. The entire window was 4 metres wide and nearly 5 metres (16 feet) tall, and we made it in several layered sections so it could easily be transported by lorry to the film set where it was finally assembled.
