In 2010, she was nominated for two Screen Actors Guild Awards: as the lead actress in the television film When Love Is Not Enough: The Lois Wilson Story and as part of the cast of Black Swan. She also reunited with Burton for Frankenweenie (2012). She has starred as Joyce Byers in the Netflix science fiction horror series Stranger Things (2016–present), for which she has received Golden Globe and Screen Actors Guild nominations; and in 2020, she starred in the HBO drama miniseries The Plot Against America.
