Harry Potter and the Deathly Hallows: Part 2

Ah, the golden age of stereoscopic conversion, when everyone wanted to wear 3D glasses in the cinema (glasses on top of my own glasses, in my case). We worked on about 35 shots for the film, creating roto for the 2D to 3D conversion. I remember spending two weeks on a single shot, layering every depth element, including some very challenging hair roto. Good times.
