Working alongside effects house Rhythm & Hues, and to a lesser degree, BUF, Look FX, Crazy Horse, Lola FX and Legacy Effects, Rocheron's team spent two years putting together what would eventually comprise 12 minutes of digital ocean. The 110 effects shots MPC completed in that time required a deep understanding of the behaviour of oceans. "This isn't the first time we've simulated an ocean", explains Rocheron, "but normally it's like throwing a ball into a bathtub and hoping the splash hits". Not this time.

"There aren't any shots in this sequence that aren't done on purpose, so when a wave hits the Tsimtsum, it's to get a particular feeling into a shot. Ang would say: 'I want to see the black ocean and then that big splash hitting the side of the Tsimtsum'. There's a performance in what the ocean is doing and how it triggers events. Nature is stronger than everything else, and this drives both the camera and Pi's action on the lifeboat."
