20 Mind-Blowing Facts You Didn't Know About Seinfeld

While rewatching Seinfeld, you may notice a lot of actors appearing in guest spots before they became superstars. The most obvious example is Bryan Cranston, who's best-known for his career-defining performance as Walter White in Breaking Bad.

In Seinfeld, he appears in five episodes as the Jerry's re-gifting dentist, Dr. Tim Whatley. However, many people aren't aware that Anna Gunn, who portrayed Walter White's wife, Skyler, in Breaking Bad, also appeared in Seinfeld. She plays Jerry's girlfriend, Amy; the woman George thinks is sleeping with Jerry's cousin.

Many of guest stars are pretty easy to spot; Courtney Cox, Sarah Silverman, Michael Chiklis, Jeremy Piven, Denise Richards; the list goes on and on. However, there are some cameos that are much harder to notice. Most people don't notice that Eric the Clown is portrayed by the director of Iron Man and The Mandalorian, Jon Favreau!

Also, there has been a rumour for years that Game of Thrones' Peter Dinklage provides the voice of James the Wake-Up Guy. Although the character sounds REALLY like him, this rumour is false. The voice was provided by Brian McNamara, who appears later in the episode.
