Released in 2010, Tangled is today’s most expensive animated film, costing $274 million to make. The movie, loosely based on the German fairy tale “Rapunzel,” earned $591 million worldwide and a nomination for Best Original Song at the 83rd Academy Awards. Despite its success, Tangled was a beast to produce. It spent six years in production, underwent a controversial name change (from Rapunzel to Tangled to draw in a wider audience), and had issues with one of its (longest) characters; Rapunzel’s hair. (Years of program writing went into creating the perfect hair simulation program.) However, perseverance won out; Tangledbecame Disney’s 50th animated film.
