A beloved children’s novel is turned into a charming animation in My Father’s Dragon, which is world premiering at the BFI London Film Festival. Oscar-nominated director Nora Twomey (The Breadwinner) helms a story of childhood friendship based on the 1948 novel by Ruth Stiles Gannett, with animation from Cartoon Saloon (The Secret of Kells, Song of the Sea, Wolfwalkers) and a screenplay by Meg LeFauve (Inside Out). It’s a sweet adventure with appeal for young kids and a starry voice cast including Jacob Tremblay as hero Elmer, and – in one of the film’s more amusing moments – Whoopi Goldberg as a cat.
