The shoot for Singapore Airlines took us on a whirlwind global tour to San Francisco, Jaisalmer in India, Paris and finally to Wuzhen in China as our gracious flight attendant shows us that attentive service with a smile is available wherever you fly.

This was an attractive script for us to work with as the flight attendant needs to seamlessly transition between each city. Actors and extras were either shot on bluescreen or with a steadycam, and the challenge was to transition the takes ensuring an exact match with eyelines, shoulder movements and hair. "This required a lot of rehearsals and several takes so I took a Shake box with me on each shoot so I could do quick comps on set and ensure we had each move exactly matching the next," said VFX Supervisor Dave Morley. "In some instances, we needed to transition the environment in a camera move as well as the actor, for example when we move from Paris to Wuzhen."

Buildings were constructed as projections for Nuke or as matte paintings and were rebuilt in the scenes with the transitions. A lot of work was done to reconstruct the environments to help trick the eye into believing you are with the flight attendant in one city, when really you have transitioned to the next. "To help this, we always had elements that crossed over, such as people moving in and out of transitioning locations," said Morley.

Careful attention was paid to lighting as each city was filmed at different times of day - San Francisco in the morning, Jaissalmer in the middle of the day, Paris in the afternoon and Wuzhen at sunset.
