What’s almost as scary as being buried alive in a coffin? Shooting a feature film inside that coffin, says cinematographer Eduard Grau.

In “Buried,” the recent Lionsgate release helmed by Rodrigo Cortes, Ryan Reynolds plays a U. S. contractor in Iraq who wakes up six feet underground, entombed in a ransom attempt after his truck convoy is attacked. With only a lighter and a cell phone for illumination and communication, he spends the next 90 minutes squirming inside his claustrophobic confines, desperately trying to inform the outside world of his predicament and whereabouts.

With not even a flashback in the script to take the story outside the dark box, and no freedom to use anything other than close-ups and tight angles, Grau had his work cut out for him.

“We thought we were going to run out of tricks,” he said, “but we kept coming up with new ideas of how to change things and make it interesting.”

In fact, the crew constructed four different coffins with removable walls on a soundstage in Barcelona — each one designed to allow specific shots. But to ensure that everything looked authentic, they were built small. “The coffin is the size it looks,” said Grau, “but you’d be surprised how much space you can find to put a camera — or even a two-camera team — in a meter and a half.”

Grau and his co-camera operator, Pau Esteve, worked “very close” to each other. “He would be shooting Ryan’s eye, I’d be shooting his whole face, in different positions. Both of us would wiggle around in that tiny space.”

While the original intent was to shoot digitally, Grau ended up using 35mm film and Moviecam Compact cameras. “Digital would have been cheaper, but we discovered that it was also going to be more difficult, and wasn’t going to look as good. Film was an artistic decision,” said Grau, who was helped by Kodak and Deluxe.

Grau relieved the monotony of the darkness inside the coffin by alternating between different light sources: the cigarette lighter casts a warm, flickering glow, the cell phone a cool blue radiance. Reynolds uses one, then the other as he struggles, twists and turns, creating varying patterns of light and shadow.

Grau credits Reynolds with an exceptional physical and emotional performance over the course of the 18-day shoot in August 2009. “It was very intense for him,” he said. “Lying in a coffin every day, he ended up full of bruises, splinters, sand on his face and an aching back.

“We had one very long scene when (his character) speaks to his mother on the cell phone. We shot it without rehearsal on the very first take. I really cried because of his performance of that intense moment. I was surprised. That had never happened to me before.”

Grau, 29, picked by Variety last year as one of its 10 cinematographers to watch, is keeping busy. Before shooting “Buried,” he was d.p. on Tom Ford’s “A Single Man.” He recently wrapped Nick Murphy’s “The Awakening” with Rebecca Hall and Dominic West in England, and has just begun Marcal Flores’ “Animals” in Spain.
