The creation of the hummingbirds took advantage of a brand-new feather system created in-house by the Framestore team. Each of the birds’ iridescent feathers - of which hummingbirds have between 1000 and 1500 - were meticulously crafted and planted onto the CG birds, matching the size and distribution of their real-life counterparts. Then simulating real world physics, Framestore’s feather system dynamically lays down one on top of the other, with precise feather-on-feather collisions to mimic their real-world look and behaviour.

One of the biggest challenges for the film’s artists was creating the flocking sequence with the hummingbirds in a believable way. The production team referenced footage of birds and fish that do perform this action, in order to produce the commercial’s realistic-feeling images.

For the birds to look as natural as possible, the team also needed to create the surroundings for them to exist in, for which it leant on the environmental experience of Framestore’s film department. Talking about how this was created, Jules Janaud, the project’s VFX Supervisor said the team: ‘created a rainforest inspired by highlands of northern and western South America, It had dense foliage, mossy trunks and flowers that added touches of colour.’ ​
