You know Them Best

Client: Grace Kelly Childhood Cancer Trust/OWB

Childhood cancer remains one of the leading causes of death among children in the UK, with just over 4,000 children and young people diagnosed each year. Created in partnership with The Grace Kelly Childhood Cancer Trust, this campaign was designed to raise vital awareness of the signs and symptoms of childhood cancer, helping parents, carers and teachers recognise when something may be wrong and take action sooner.

At the heart of the campaign was a cinema advert inspired directly by lived experience. To ensure authenticity and emotional truth, children affected by cancer and their families were invited to a creative “doodle day,” where they took part in fun, expressive sessions of drawing, painting, writing and play. The artwork they created became the foundation of the campaign’s visual identity, shaping the tone, style and spirit of the final film. The advert was built around the message “You know them best,” reinforcing the idea that those closest to a child are often the first to notice subtle changes. The animation style honoured the children’s original drawings through hand-crafted character design and frame-by-frame detail, creating a distinctive, human look that felt personal and powerful. The film and wider campaign were created to generate measurable awareness and engagement, sparking conversation across editorial and radio channels while equipping audiences with knowledge that could ultimately help save lives.
