Maya Erskine and Anna Konkle were both 31 years-old portraying 13 year-old versions of themselves during production; however, the rest of their classmates are played by real-life middle schoolers. This made filming the 'R-rated' scenes a bit challenging and in some cases body doubles were hired.
Throughout the first season you can see a poster of 90's heartthrob Jonathan Taylor Thomas on Anna's bedroom door. Richard Karn, who plays Maya's father, starred in the sitcom 'Home Improvement' with Jonathan Taylor Thomas.
It was previously reported that during filming of the first season, Maya Erskine was 31 years-old and Anna Konkle was 24 years-old. Both actresses were actually the same age, 31, during production of the first season. They met while studying abroad during their junior year of college at NYU.
In Episode #8, a group of kids watch the movie "Wild Things," mainly to see the infamous sex scenes. Co-creator Maya Erskine's real-life father, Peter Erskine, is the actual drummer on the "Wild Things" soundtrack.
