Mum wrote, directed and starred in 2005's "Yam Yasothon" ("Hello Yasothon"), in which returned to his roots as a nightclub comedian for a musical romantic comedy set in rural northeastern Thailand in 1967. It was an homage to the Thai musical comediess of the 1960s and '70s, especially the films of Mitr Chaibancha and Petchara Chaowarat. The dialogue was entirely in the Isan Lao dialect, and for screenings in Bangkok it Thai subtitles so that central Thais could understand it more easily. In the Thailand National Film Awards, "Yam Yasothon" received a best-actress nomination for Mum's co-star, Janet Kheaw.
