Visual effects company Cinesite has given us a glimpse behind the scenes on The Monuments Men, showing how it transformed the look of several scenes in the new World War II movie directed by George Clooney.

Cinesite VFX Supervisor for the film Jon Neill worked with The Monuments Men's overall production VFX Supervisor Angus Bickerton on several sequences, including an impressive scene that shows Campbell, played by Bill Murray, turning on the lights in an underground salt mine to reveal hidden treasures (right).

To create that particular sequence, Cinesite used photogrammetry reference of the objects that were on set to create models, which were laid out in a Maya scene and lighting rig.

"An image was rendered from a fully ray-traced, global illuminated scene with all the lights switched on," Cinesite explains in a press release. "The team set up a script in Nuke where light passes could illuminate the background in any order, by bringing through the beauty pass and adding proper directional shadows. In the final shot, the flickering light gradually reveals the depths of the cavern."
