New York City-born Erin Moriarty launched her acting career in a way many hopefuls dream of: with an awards-recognized project. Erin first appeared on screen in the Emmy-nominated soap opera One Life to Live (1968) in 2010, playing the character Whitney Bennett in six episodes. In 2011 she built on her TV work with a guest role in an episode of Law & Order: Special Victims Unit (1999).
The following year, Erin landed a small part in her first feature film. Acting alongside Ben Stiller, Vince Vaughn and Jonah Hill, she appeared in the sci-fi comedy The Watch (2012). In 2013, she took another supporting gig in a movie. The coming-of-age drama The Kings of Summer (2013) follows three teenagers who hatch a plan to part ways with their parents and live off the land in a house built by themselves. Portraying Natalie Walraven, the daughter of Radha Mitchell's character, Erin also worked on the 2013 TV series Red Widow (2013).
