The Harry Potter star has signed up to a scheme run by children's charity Plan, which encourages the public to give money to help youngsters in poor countries survive the harsh conditions they are living in.
Spall, who has three grown-up children of his own, has now spoken out about his involvement with the campaign, revealing he enjoys knowing exactly where his contributions are going.
He says, "My family has been sponsoring a child with Plan for many years now - it's a very interesting and rewarding way to give. It's great to feel we are part of something where we know where our contributions are going.
"The work is all to benefit communities, we know, but having a child as the focus makes it all very personal and involving."
