Love, Simon tells the story of Simon (Nick Robinson), a teen who hasn't come out to his friends when he falls for an anonymous classmate online. Simon's decision to come out is taken out of his hands when another classmate outs him on the internet, leading him to share his sexuality with his friends and family, while also trying to figure out exactly who he has fallen in love with. By his side throughout the entire movie is Langford's Leah, his funny, sometimes insecure best friend, who is nurturing a major crush on Simon.
As Leah, Langford gets to play a lighter character who is quirky, loyal, and a complete joy to watch. In fact, Leah could get her own movie, considering the character is the focus of the sequel to Simon vs. the Homo Sapiens Agenda, the book on which Love, Simon is based. Fingers crossed that Hollywood tells the rest of Leah's story, because more of Langford on the big screen can only lead to good things.
