Though Joni Mitchell shot down the idea of Taylor Swift playing her in a biopic, we think Looking for Alaska and Sierra Burgess Is a Loser actress Kristine Froseth would also be a good candidate for playing the Canadian folk legend. Froseth doesn't play the guitar or sing as far as we know, but we have a feeling she could learn to fake it convincingly enough (and really, who could actually master Mitchell's vocal range?).
