Keira Knightley is making her U.S. television debut as the voice of Tinker Bell in Syfy's four-hour live-action miniseries Neverland.

The Oscar-nominated actress joins Rhys Ifans, Anna Friel, Bob Hoskins, Charles Dance, Raoul Trujillo and Charlie Rowe.

Written and directed by Nick Willing, Neverland centers on Peter (Charlie Rowe) who, along with his pals of young pickpockets, have been rounded up by their mentor Jimmy Hook (Rhys Ifans) to snatch a magical orb that transports them to another world - Neverland. Filled with white jungles and imposing cities formed out of trees created by Dr. Fludd (Charles Dance) and inhabited by a colony of tree spirits led by Tinker Bell (Keira Knightley), this mysterious realm welcomes unknown friends and enemies snatched from time. These include power-mad Elizabeth Bonny (Anna Friel) and her band of 18th century pirates who search for the answer to eternal youth, a secret guarded by a Holy Man (Raoul Trujillo). As the fight to save this strange and beautiful world escalates, Peter and his crew consider that growing old somewhere in time could be less important than growing up -- right here in their new home called Neverland.

Keira Knightley will record her role this spring. Neverland will air on Syfy in December.
