Tom Felton is encouraging fans to give generously to a fund set up for a five-year-old cancer patient.
Jack Marshall was diagnosed with a brain tumour just after he began school, and he later sustained brain damage from high-strength chemotherapy treatment.
The Harry Potter actor is pledging his support to the Jack Marshall Brain Tumour Fund and has asked his devotees to follow his lead.
In a post on his Twitter.com page, Felton appeals for donations from "anyone who can possibly help and would like to", sharing a link to Marshall's fundraising website.
The cash will be used to pay for the youngster's ongoing treatment and to raise awareness of childhood brain tumours.
