“Lost in Thailand” (2012) is arguably not a “cult film” since it’s one of the highest grossing films in China, though it might be considered one in the U.S. where it’s relatively obscure. The film was written, produced, and directed by Xu Zheng, who also starred in the film as Xu Lang, the inventor of a miraculous new energy source. In order to get added funding to develop his innovation he needs to get a signature from his company’s largest shareholder who happens to be in Thailand. Xu’s quest is made more difficult than expected due to the antics of Wang, a comically annoying character he meets on the flight to Thailand, and Gao, a rival scientist secretly tailing them.
