The 1980 Loretta Lynn biopic Coal Miner’s Daughter — which airs tonight at 8pm EST on TCM as part of their “Mary Stuart Celebrates Music in the Movies” series — first hit theaters over four decades ago, but its legacy still shines just as bright today. Charting Lynn’s rise from a poor, teenage bride to one of the most famous country music artists of all time, it did more than tell a good story — it also cemented Sissy Spacek‘s place in Hollywood, earning her her first (and only!) Best Actress Oscar, and honored one of country music’s greatest voices.
But even if you’ve watched it a dozen times (and can sing every word to “You Ain’t Woman Enough”), there’s a good chance you’ve missed a few behind-the-scenes gems. In honor of both the screening and the late Loretta Lynn’s birthday (April 14), here are some interesting facts about the film.
