Progression still 1 of 6. To start the shot of the Tweedles in the Red Queen’s throne room, Matt Lucas (on the left) is photographed on the green-screen stage wearing the “Tweedle suit,” designed to stimulate the characters’ body shapes and movement. While the Tweedles’ bodies are ultimately animated, Lucas’ actual movements are captured on film and used as a basis.
Progression still 3 of 6. A reference shot incorporating both Lucas’ facial performances (which will later make their way into the final shot) is handed over to layout and animation, where the body performances (incorporating Lucas’ on-set performance) are created.
Progression still 4 of 6. The Tweedles and monkeys are placed in the layout of the Red Queen’s throne room. Lucas’ facial performances float above the animated character for matching. For the effect to be seamless, the animation has to be very precise.
Progression still 6 of 6. The final composite shows Lucas’ color-corrected facial performances perfectly aligned with the computer-generated head. The lighting, reflections, shadows and surface texture all combine to produce vivid characters in a fully-realized world.
