Fast & Furious (4) opened in early April to the biggest box office opening of the year (at the time).  Ian Failes talks to Double Negative about their tunnel chase scenes, and Rhythm & Hues exploding tanker sequence.

Kirk: We use Maya in-house for our modeling. So we had a bunch of talented artists sculpting in Maya for quite a long time to create that look, working from reference as much as possible. We also have a proprietary system called dnAssets, which is a tool that lets us store vast amounts of data ready for rendering. We can lay the models out in a scene in a crude, proxy fashion as simple geometry that later on in render time becomes full-res.
