Tim Roth will star in the title role for Sky One's drama Skellig, which will premiere on TV next spring, and have a subsequent theatrical release.

According to Variety, Skellig is directed by Annabel Jankel and based on David Almond's hit tyke novel. The film also stars Kelly MacDonald, Bill Milner (Son of Rambow) and John Simm (Life on Mars).

Set in the North of England, the film recounts the story of a boy (Milner) who finds the mystical Skellig -- part owl, part angel -- living in the garage of his new home.

MacDonald and Simm play the boy's parents.

The film began principal photography in Cardiff, Wales, on Tuesday.
