Crazy Tsunami is a 2021 Chinese disaster monster movie about a series of huge waves that flood a city and create a deadly peril. Unfortunately, this means that the human survivors have to contend with crocodiles that have been washed into the remains of the partially submerged buildings.
Directed by Zhou Jiuqin and starring Rong Fei.
The film is obviously a take on Crawl (2019) which features characters trapped with alligators after a hurricane in Florida.
