Framestore was involved early on in the pre-production process, with a team of animators tasked with spending six months carrying out animation tests at Leavesden to help the directors plan the sequences and develop the alien characters.

First came the Keepers. Creepy by design, they are a group of slinking aliens able to cloak themselves from sight. 'The Keepers appear in a number of really nightmarish scenes, and work more as creatures of the night than traditional aliens, so we gave them these reversible knees and elbows which made them quite insect-like', explains Animation Supervisor Max Solomon.

The Sargorns were a different prospect – powerful and capable of speech, these winged reptiles provided an animation challenge as they flicked between calm conversations with humans and moments of bestial rage. Their long, lizard skulls made dialogue interesting, especially as their teeth are fused to their lips. 'We had to find the right balance of flexibility within the constraints of that, so we made them talk out of the side of their mouths where there are fewer teeth', adds Solomon.  Once they entered fight mode the emphasis fell on making them as animalistic as possible – moving on all fours and using their tails, or beating their huge leathery wings.

An impressive fight takes place between Caine and one Sargorn, Greeghan, in Balem’s boardroom – a huge digital environment constructed by Framestore. Below the cavernous, gilded hall of the boardroom is another Framestore environment, a gruesome DNA laboratory revealed through the floor, which can be made transparent in an instant.

The fight that rages through these environments was a combination of practical and visual effects, transitioning seamlessly between real-life stunts and full CG shots. Ramps were built in the partial Balem’s Lab set, which allowed Channing Tatum to skate as if he was using jet boots. The team then removed the ramps, added Caine’s boots and animated the pursuing Greeghan. With the environment built in CG, Framestore's artists were able to replace camera moves when necessary, and create fully CG shots with a Caine digi-double for any shots that were impossible to film practically, such as when the pair crash through a pane of glass. 

As well as environments Framestore also created several of Jupiter Ascending’s spaceships. The most complex, Titus’ Clipper, is introduced with a majestic sweep through the icy rings of a planet. At three kilometres long, and consisting of around a billion polygons, it was Framestore’s biggest model to date, a much bigger construct that the International Space Station (ISS) in Gravity.

It is more lavishly detailed than the ISS too: 'a floating city, with a city’s worth of architecture', as Montréal VFX Supervisor Chris Lawrence puts it. 'Part of the challenge was giving the model enough richness to sell the scale while still looking functional – a challenge the modellers were very happy to solve'. The dock the Clipper arrives in is just as grand, a sprawling palatal environment with hundreds of individually placed lights and lots of reflective grand architectural detail. A small section of it was shot practically – a single floor for the actors to walk across, surrounded by green screen.
