Like other Saloon films, the film was hand-drawn. The film began production soon after the release of The Secret of Kells (2009), premiered at the 2014 Toronto International Film Festival on 6 September in the "TIFF Kids" programme.[6] The film had a limited release in certain countries, but received overwhelming acclaim and was nominated for the Academy Award for Best Animated Feature at the 87th Academy Awards in 2015.[7][8]
