In a radical departure from his villainous turn as Loki in Marvel's The Avengers and Thor: The Dark World, Tom Hiddleston has signed on to play country music legend Hank Williams in the biopic I Saw the Light.

The story will chart Hank Williams' speedy rise to fame and fortune, and the toll it took on his personal life. The musician, best known for hit songs such as "Your Cheatin' Heart", "I'm So Lonesome I Could Cry" and "Hey Good Lookin," passed away at the age of 29 from heart failure.
