What follows is a sort of hip-hop Billy the Bass meets Busby Berkeley meets Finding Nemo number, as assorted seahorses, lion fish, yellow tangs, neon tetras and butterfly fish disport themselves around the tank, both individually and in aquatic chorus lines.

VFX Supervisor and Lead Inferno Artist for the project was Ben Cronin, veteran of many a Dom & Nic project, including Believe.

The pre-viz gave us a chance to block out some of the big chorus sequences, though not as many as we’d hoped, time being against us." A two-day shoot off Brick Lane saw the necessary plates captured, with challenges successfully overcome including cloudy tank water and a malfunctioning periscope camera.

"One thing that really helped along the way," enthuses Lighting TD Simon French, "Was a brilliant dynamic script developed by Junior TD Henry van der Beek for animating the fins and other features. It was a massive time-saver in the animation and brought an extra level of realism to the renders."
