The movie follows his upbringing in Baltimore, his passion for creating and performing with puppets; how he began working for Children's Television Workshop (now Sesame Workshop) and his career there, including rising to executive producer, and how his most popular creation came to be.
Compare I Am Big Bird, another independent documentary about a longtime Sesame puppeteer (Carroll Spinney).
This film provides examples of:
- All-Loving Hero: When defining Elmo's personality, Clash decided that he should "represent love" and made him a Cuddle Bug. It succeeded way beyond expectations.
- Ascended Fanboy: Clash was a big fan of Jim Henson and decided to become a puppeteer. Then he was recruited by the man himself.
- Happier Home Movie: Shows up a few times in the film including one where his newborn baby just arrived at his home and had to talk in Elmo's voice much to the annoyance of his wife.
- The Pete Best: An In-Universe example. In 1985, Richard Hunt was fed up with having to perform Elmo and tossed the puppet on Clash's lap. Clash raised him up and brought energy, life and a definitive voice in him. The character was then developed in a major way and became one of Sesame Street's most popular creatures, mostly thanks to Clash.
