"Klaus," Netflix's first animated film, is an origin story of Santa Claus. Because the Oscar-nominated movie appeals to nostalgia, director Sergio Pablos and his team at The SPA Studios in Madrid decided to make the film in 2D.

Insider spoke with Pablos to find out how they made the innovative film, which earned an Academy Award nomination for best Animated Feature and seven Annie Awards.—Anonymous
