Milana Vayntrub made her acting debut with a guest appearance in three episodes of the NBC television series ER back in 1995. Alongside Stevie Nelson, she co-founded the YouTube comedy channel Live Prude Girls, where they produced numerous short comedy sketches. Live Prude Girls gained recognition and was featured on NewMediaRockstars’ Top 100 Channels countdown, securing the 93rd spot. Throughout her career, Vayntrub has taken on small roles in both film and television, including appearances in projects such as Life Happens and Silicon Valley. She has also been featured in several comedy videos on CollegeHumor.
From 2013 to 2016, Vayntrub portrayed the role of Lily Adams, a saleswoman, in a series of TV commercials for AT&T, reprising the role in 2020. Additionally, she played Tina Shukshin as a series regular on the Yahoo! Screen series Other Space in 2015, created by Paul Feig. The following year, she appeared in Feig’s Ghostbusters reboot alongside Other Space cast members Neil Casey, Eugene Cordero, Bess Rous, and Karan Soni.
Between 2016 and 2017, Vayntrub appeared in the television series This Is Us, portraying the character Sloane Sandburg. In July 2017, she was cast in the lead role of Marvel Comics superheroine Squirrel Girl in the New Warriors television pilot for Freeform. However, the series did not move forward, and despite efforts to find another network, it was ultimately cancelled. Despite this setback, Vayntrub voiced Squirrel Girl in the Marvel Rising franchise and starred in a six-episode scripted podcast from Marvel and Sirius XM titled Marvel’s Squirrel Girl: The Unbeatable Radio Show. Also in 2017, Vayntrub starred in the Eko interactive streaming television series That Moment When as Jill.
