Patrick Frater Asia Bureau Chief Hong Kong-based indie sales agent Autumn Sun comes to FilMart with a bulging slate of new film titles from around Asia — including two animated features from mainland China. Autumn Sun, headed by sales veteran Elliot Tong, is giving a market premiere to “Planet Cat,” an animated feature by Song Yuefeng (“Ping Pong Rabbit,” “Throne of Elves”) about a chance meeting between a stray cat and a girl in a city at night. The film is produced by Nuctopus Studio and Dreamers Studio and previously won a development prize at the Beijing International Film Festival. The feature is now in post-production and a promo reel is being screened at the market.
