Hung was the subject of a documentary called William Hung: Hangin' with Hung, a ninety minute film recounting his sudden rise to fame. Hung appeared as himself in a February 2006 episode of the television series Arrested Development titled "Fakin' It", acting as the front-man of a band, "William Hung and his Hung Jury", the house band for a fictional courtroom-themed show Mock Trial with J. Reinhold.

Hung has appeared in an episode of the MTV Show, Celebrity Deathmatch, where he battles Ricky Martin (who performed the original "She Bangs").
In the episode Sexual Harassment of the American version of The Office, the letters "WL HUNG" appear on Todd Packer's vanity plate and is mistaken to be a reference to Hung. The letters actually stood for "Well hung".
He has also appeared in Airline in which he missed his flight, then sang his infamous song once again for the cameras.[5]
