Blue Scar is a 1949 British drama film directed by documentary filmmaker Jill Craigie and starring Emrys Jones and Gwyneth Vaughn. Set in a Welsh village where the mine has recently been nationalised, it focuses on the relationship between Olwen Williams, a miner's daughter who leaves the village to live in London, and Tom Thomas, who dedicates his life to working in the mine. With Craigie's background in documentary films with a social message, Blue Scar was designed to raise questions about the value of nationalising the coal industry. It was the only non-documentary film Craigie directed.
