Walt Disney Co has taken three Chinese firms to court over concerns Chinese animated film The Autobots copied elements from Disney’s own hit movie Cars. The dispute was over “copyright infringement” and “unfair competition”, according to a notice on the Shanghai Pudong New Area People’s Court website. Disney is making a major push into China with the recent opening of a USD5.5 billion theme park in Shanghai, its first in mainland China, while its animated movies, including Zootopia and Big Hero 6, have been big box office hits in the country.
