Luka Wolfgram used to talk about moving to New York with his little brother, Kosta, to live their dreams.
His short film Our Superheroes, a heartbreaking meditation on loss, is about Kosta, who died, aged 8, from a brain tumour in March last year.
In October, Luka, 13, will be going to New York after his film was selected as part of the 2017 All American High School Film Festival, the world's largest high school film festival.
