The Mortified Sessions is an American documentary talk show on the Sundance cable television channel, hosted by David Nadelberg. The series, which premiered in December 2011, features interviews with one or more celebrities each episode, showing photos and artifacts from their childhood. The show serves as a companion piece to Mortified, a live stage show Nadelberg created nine years earlier in which people share excerpts of their childhood writing and art before an audience of total strangers in order to reveal a story about their life. The stage show launched a series of books and web content, has been featured numerous times on public radio's This American Life, and there are plans for a Mortified documentary.
