I worked on the first Doctor Strange teaser trailer, very early in the project while things were still getting setup and the crew was yet to be allocated. We had a couple of weeks to do some environment extensions on 3 shots in the Hong Kong - a sequence which would eventually become the climax of the film. As it was still very early in the project, a lot of the asset development was still underway, so these shots turned into a bigger compositing task than they might otherwise have been. As the only compositor on the show at the time, it was a lot of work in not a lot of time. But it was an interesting challenge and I think the shots turned out well in the end.
