Shelton tells The Frame that it a laggie — a term coined by the screenwriter Andrea Seigel — is someone who lags behind. In the film, Keira Knightly plays the one who is lagging behind her peers. She's a 20-something having a quarter-life crisis and is deviating from the traditional approach to adulthood that everyone around her is taking.
In her angst, the Knightly character befriends a 16-year-old girl played by Chloe Grace Moretz and escapes into her teen life. Shelton was drawn to the script in part because of their unusual friendship and likens it to the unconventional romantic relationship in "Harold and Maude."
Shelton, whose credits include "Humpday" and "Your Sister's Sister," also says she wanted to make a movie about a female protagonist who is "flawed and make mistakes." She wanted to carve out territory on the big screen for a young woman to go through the crises so often portrayed by male characters in movies such as "The Graduate."
