Tildypops is a semi-autobiographical, coming-of-age film, co-directed by Tiggy Bayley and Oscar Downing. It follows the life of 16-year-old Tiggy as she grows up with an autistic brother and uses the device of manic marathon training to parallel the journey of coping with a neuroatypical sibling. The film tackles broader relatable themes of female adolescence, insecurity, teenage infatuation and self-acceptance.
