Elizabeth Olsen has signed on to star alongside Tom Hiddleston in the Hank Williams biopic I Saw the Light. Tom Hiddleston signed on to play the country music legend back in June

The story is adapted from the 1994 book Hank Williams: A Biography, by Colin Escott, George Merritt and William MacEwen. Elizabeth Olsen is playing the singer's wife, Audrey Mae Williams. The producers have obtained the rights to Hank Williams' songs, such as hits "Your Cheatin' Heart," "I"m So Lonesome I Could Cry" and "Hey Good Lookin'", which will be sung by Tom Hiddleston himself.

Born in 1923, Alabama native Hank Williams' music career took off after World War II with his first hit, "Move It On Over." He struggled with addictions to alcohol and prescription medication, while suffering from spina biffida, before passing away at the age of 29 due to heart failure.
