Katherine McNamara is currently starring in CBS All Access's adaptation of Stephen King'sThe Stand as Julie Lawry, a small-town girl with a wild streak who also happens to be a not-so-great person. It makes the character a good fit for Randall Flagg's (Alexander Skarsgard) group of survivors in an anything-goes New Vegas, but also makes her very different from who most fans are used to seeing McNamara play. The actress is perhaps best known for her heroic roles as Clary Fray in Freeform's Shadowhunters and Mia Smoak in The CW's Arrow. With both of those characters being very popular with fans, McNamara is no stranger to the power of fandom but she says she's learned a lot about boundaries from it as well.
