Before and Afters:

The final shots would feature live-action photography, and significant digital environments and effects simulations from Sony Pictures Imageworks. To help make Imageworks’ shot ‘sit’ in the plates and to deliver the most dynamic scenes possible, the film’s visual effects team embarked on an enormous effort to replicate the surroundings digitally.

This involved the use of Lidar scans, extensive reference photography and a huge model and texture build.

It’s always a little mindboggling to see the effort that goes into these kinds of shots.
