Harry Potter star Katie Leung and The Danish Girl’s Rebecca Root will also voice characters in the animated production.

Steadman said: “I was so thrilled to be asked to take part in Moominvalley. It’s such a brilliant show and different from anything I’ve ever done before.”

Moominvalley is based on the beloved Moomin stories by Finnish-Swedish artist Tove Jansson and will consist of two series, broadcast in 2019 on Sky One.

The Moomins are one of Finland’s biggest exports and were recently the subject of an exhibition at London’s Southbank Centre.
