The Art of VFX interviews
James Cooper, the lead compositor on Cosmopolis and he discussed the
film's visual effects at length and mentioned Rob. Here's an excerpt of
the interview + new images from the film.
Sometimes Eric Packer occults the windows limo. Was there an on-set effect or is it your work?
It was a combination of both, actually. Initially that was to be a
practical effect but David wanted to have options as to when the windows
became fully opaque and when they returned to tinted transparency. To
this end he shot the parts of the sequences where he was certain they
would be opaque practically but left numerous shots on the front and
back end of those shots as greenscreen. This allowed him much more
control as to the timing of when the windows fell into darkness and for
how long and gave us references as to what they would look like fully
darkened.
Can you tell us about the design of the various screens inside the limo?
The character of Eric sees much more than just price and volume
variations. He has a unique ability to look at the many different
patterns that the volatility of the stock, commodity futures and money
markets generate, analyze them and predict where they will end up in the
near future. Keeping that in mind we started with the production design
references and adapted them, adding our own design elements and
animations to create more visually interesting screens than might
normally be seen on a trader’s monitor.
Can you explain to us the shot in which Eric shots in his hand?
Well, in terms of visual effects I can. For motivation you’ll have to
talk to Mr. Cronenberg. Apparently Robert Pattinson and his handlers
balked at the thought of doing this as a practical effect so he just
pointed the (unloaded) gun at his hand and pulled the trigger. We added
the muzzle flash, smoke, wound and blood splatter in compositing.
Is there an invisible effect you want to reveal to us?
A particularly challenging shot has Eric entering an alleyway on a
mission to confront his stalker. We needed to replace the building at
the end of the lane way for continuity purposes but Eric passes through a
chain link gate which is left swinging behind him. And, of course, the
camera is moving as well. Production did not have a green screen big
enough to cover the entire entrance to the lane way so we rotoscoped the
gates, put them on cards in 3D space, tracked the camera and animated
the roto to match the actual gate. All in all a very tricky shot.
What was the biggest challenge on this project and how did you achieve it?
Well, of course, making the driving shots believable was a challenge,
particularly since David has a slightly surreal aesthetic even in his
more, shall we say, realistic films. I’m not sure that he wanted the
cityscape outside to feel too real. I would say the biggest technical
challenge was in the keying. He wanted to shoot the interior of the limo
with tinted windows in place in very low light. This presented some
challenges in that the green screen luminance was considerably less than
optimal and, because of the high ISO needed to shoot in such low light,
was much grainier than ideal as well. Of course we wanted to keep every
hair on everyone’s head in the keys so we spent a lot of time finessing
them.
