Born to Lao and Vietnamese parents, Mattie was raised in Los Angeles, but returned to Laos a decade ago. Her debut film was the first Lao film to screen outside of SE Asia. The film’s success led to Mattie’s selection for the Cannes’ Fabrique des Cinémas du Monde, TIFF’s Directors Talent Lab, and Berlinale Talents. Mattie helped the Lao government create the infrastructure necessary to bring foreign co-production to Laos, and she produced Laos’ first American and Japanese co-productions. Her second film, Dearest Sister, was Laos’ first submission for the Foreign Language Award at the 90th Academy Awards. Her latest film, The Long Walk, premiered in the Giornate degli Autori at the 2019 Venice Film Festival, Toronto International Film Festival, Tokyo, Rotterdam, and Busan. The Long Walk garnered a Best Director prize at Sitges. Mattie is Laos’ first, and only, female filmmaker.
