The latest Nationwide advert, for its SavingsWatch service, was created by the Moving Picture Company (MPC) along with 18 Feet and Rising.
The agency was appointed to help create a hybrid between photo-real and a paper pop-up storybook.
Two most spots in the campaign will follow this month.
Philippe André, director from Independent, said: “From the pre visualisation to the shoot then to post production, this spot has been a great collaboration with MPC, not only technically but creatively.
“The team immediately understood it was really the story I wanted to focus on: to see a pop up world through characters’ eyes, to reveal this world from the inside. And of course to keep it warm, human, and never technical. It was a real challenge creating a balance between the real world looking believable in a pop-up world and at the opposite end, creating a world not perfect enough that it ran the risk of looking like bad CG. The team at MPC worked incredibly hard to deliver this spot in 3 weeks and I’m very pleased to have collaborated with them.”
