Mill Chicago Head of Production Andrew Sommerville said of the birds, "Historically, Jeff & Wayne had always been a combination of puppets and live action birds. Bringing them into CG allowed us to give them a wider range of expression and performance than had been possible in the past, which in turn really opens up the creative possibilities of the campaign. That said, we wanted to stay true to their origins and not push their look or behavior into a cartoon world. We took our design cues from many different types of birds – the Australian magpie being our main source of inspiration"

3D Lead, Adam Carroll added, “It was important for us that Jeff and Wayne felt like real birds with a bit of personality. This was especially true when it came to the animation and capturing the nuances of how birds fly, land and hop through the world around them. We did extensive research and testing on the feathers that cover a bird’s body in order to accurately simulate them. The result was thousands of individual feathers and textures that allowed us to achieve the final look.”
