First of all, it should be noted that the release of films in China requires the approval of the State Film Administration. This approval process is not smooth sailing, and it usually requires strict review and evaluation. In the past few years, many foreign films have been banned from being shown in China because of their sensitive themes or politically sensitive contents. So some people speculate that Raytheon 4 may have encountered similar problems.
Secondly, it is reported that there are some problems between the partners of Marvel Comics and China. The partner of Marvel Comics in China is Warner Bros., and the China branch of Warner Bros. recently suspended its operation due to some internal problems. This may have affected the release plan of the film in China.
Finally, we need to note that although China is one of the largest film markets in the world, in the past few years, there have been some changes in the policy of introducing foreign films into China's film market. For example, last year, China limited the number of imported foreign films to 34, and stipulated that the world premiere time in Chinese mainland should not exceed 30 days. This may be one reason why Thor 4 failed to be shown in China.
In short, although we are not sure of the exact reason why Thor 4 was not shown in China, we can be sure that it may be related to the policy and censorship of the China film market, and it may also involve the problems between Marvel Comics and its partners in China. Whatever the reason, we hope to see this highly anticipated film in Chinese mainland cinemas in the near future.
