"The low-budget short was planned over two months and shot in just 3 days. Music for the silent film was composed and arranged by Vincent Lee, another member of JubaFilms. The German team found Justen Beer, the young star of the film, online and contacted his family to see if they had any interest in the project."
"Beer, now 12, is a break dancer for the group Hustle Kidz. 'We were not only fascinated by his dance moves, but also by his acting and his dedication during the shootings,' said Bam and Bao."
