Blake DeLong graduated from Lake Highlands High School in Dallas, then majored in History and played in rock bands while attending The University of Texas at Austin. He began appearing in new and experimental plays in the Austin theater scene in the early 2000's. In 2014, he was nominated for a Lucille Lortel Award recognizing his work in the Off-Broadway smash "Natasha, Pierre & the Great Comet of 1812". His other stage credits include roles at Rattlestick Playwrights Theater, The Public Theater, and New York Theater Workshop, where he appeared alongside Daniel Craig in Othello. Matt Muir's 2014 SXSW selection, Thank You a Lot (2014), introduced DeLong to American and international cinema audiences.
