In the end, the hard work appears to pay off, as Bubble looks like one of the coolest effects in the entire film — which is seriously saying something.
Another significant aspect of Valerian and the City of a Thousand Planets revealed by that video is the sheer amount of hard work that The Fifth Element director and Rihanna have put into the project’s visual effects.
The techniques used in these sequences ranged from putting the beloved pop star in full hair and makeup to making her wear a full body mo-cap suit to recreate her alien appearance digitally.
Bubble has the ability to change her physical form and alter her appearance in a variety of different and exotic ways throughout the Valerian story, so (despite how seamless it looks on the screen) quite a bit of effort was put into the process of making everything look as realistic as possible.
