A platform of unsuspecting rail passengers are overcome with both joy and balloons in this fun spot for the Orange Canary and Dolphin packages. An average day begins, for commuters and casual travellers alike, when their train pulls into station and they gather around the doors. As the doors open however, a deluge of colourful balloon animals in the shape of the various packages on offer burst out and swirl over and amongst our enthralled travellers. There are a variety of reactions, from astonished amusement to joyous spontaneity, with people batting, bouncing, chasing … and eventually choosing the balloons.

The limitations of 'directing' physical nylon balloons on set meant that a substantial amount of balloons required in a given shot (sometimes all of the balloons in a shot) needed to be created in CG. A vast amount of work was channelled into replicating the very specific and complex look of the orange animals, the way they react with the changing light conditions in such a huge space, and the cumulative effect that they have on each other. Animating the animals posed another challenge, as the physical balloons shot on set were heavy without helium and didn't move in the light 'care-free' fashion favoured by the director and creative team.

Extensive cleanup was required to nearly all of the back-plates to allow the balloons to appear as though they are moving in amongst the commuters, as well as to remove pieces of physical kit used in the suspension of the physical balloons. Duncan Malcolm put in long hours integrating and compositing the 3d balloons into the live-action footage.
