A Chinese tourism company is suing Paramount Pictures and a producer of the movie “Transformers: Age of Extinction” saying they had failed to show the company’s logo in the movie. Like other Hollywood filmmakers, Paramount has been eager to cash in on robust box-office revenues in the world’s second largest film market. Chongqing Wulong Karst Tourism Group, which manages the Wulong Scenic Area in southwest China, said it had lodged a lawsuit seeking 20.8 million yuan ($3.36 million), against Paramount and the 1905 Internet Technology production company, in a court in Chongqing city for reneging on their contract. A spokeswoman for Paramount, a unit of Viacom, declined to comment.
