A few of the tricks we used on this one- the vehicle exteriors were CGI, for code-red reasons. The interiors, we shot in a day in the studio. The family is a real family (and I think it shows), except for the very patient grandpa! Lastly- the beach campfire shot was done at 3pm. An exceptionally high tide the night before swept away half the beach, and meant that it would be under water by sunset. We added a few strobes, and got a great day-for-night look.
