The opening shot establishes a steel globe in
an exhibit-hall pavilion, coming to life from an artist's conception
seen printed in a newspaper. Fireworks from our library of elements
are composited behind the scene, and a CGI monorail drives through
to complete the match to the artwork.
The camera tilts down to find the main characters walking through
the Expo. Lola VFX preprocessed the plate to create a "skinny
Steve" version—dramatically downsizing the actor.
Plates for the sequence were shot in England, outdoors on an
empty paved lot surrounded by large green screens The scheduled
shoot day came with miserable weather. Steady mist and rain were
falling and wind tore the lighting silks. The show must go on
though, and the actors did a remarkable job ignoring the conditions.
The mist obscured the green-screens and background action, so
a great deal of rotoscoping was needed to extract the characters
and color-correct them in groups to restore the proper sense of
depth. Individual raindrops were painted out. Hopefully the audience
is unaware of the stormy weather in the finished sequence.
