    • She was twenty during the filming of 13 Reasons Why's first season, playing seventeen year old Hannah. Given that the show revolves around topics such as suicide and sexual assault (and graphically depicts them), it's unsurprising they went with a slightly older actress. The last time she played the character in the fourth and final season, Langford was twenty-three during filming.
