In terms of the challenges, the engine's design and modeling were a complex undertaking. It had to be believable, and more importantly look really cool. We love cars (please refer to our Pinterest page: http://pinterest.com/tendrilchris/car-boner), but we aren't engineers. Figuring out what engine parts to feature and finding the balance of cool versus realistic required a lot of research and design iterations. On top of that, most cars of this type completely conceal the moving parts of the engine beneath a plastic or carbon fiber casing. In this case though, we wanted to expose all the cool looking bits and pieces.
On a tech level (for those curious) 3D work was executed in 3DSMax with Vray for lighting and render, compositing in Nuke, and FX and title animation in After Effects. The colour seperation effect you see throughout was inspired by the double exposure work of photographer Yulia Gorbachenko. Both music and colour are meant to have a slight retro-synth flavour that compliments the palette of the boot as well as the Italo-supercar metaphor that is pervasive throughout the film. Enjoy!
