Dan Harmon has a huge following from his Community and Harmontown life but now the multitalented writer is developing a show on FX. Dubbed Happy City, the series is a collaboration between Harmon's Starburns Industries and comedy group Extremely Decent. Deadline reports that the show is described as Thomas The Tank Engine (or Theodore the Tugboat) for adults. Happy City is about a young taxi named Tyler and his friends, a helicopter and firetruck who are all millennials. The show is said to have the same visual style of Thomas the Tank Engine so think bad, Canadian CGI. But adult themes like relationships, workplace issues and self-identification will be covered. Happy City sounds interesting already but expect the meta surrealism you've come to expect from Harmon too.
