Filmed on location in Wales, On the Black Hill is adapted from the novel by Bruce Chatwin. This is the story of two Welsh brothers, identical twins. The film covers 80 years in the sibling's lives, touching upon their hopes, disappointments, romances and political entanglements. Rather than going the traditional split-screen route, two genuine twins are cast in the leads: Mike and Robert Gwilym. The stellar supporting cast includes Gemma Jones and Catherine Schell.
