Richard Keith, 72 – $1 Million

Keith Thibodeaux, also known as Richard Keith, first came under the spotlight as Little Ricky on I Love Lucy when he was just six years old. Even though he only got one year on the sitcom, it was more than sufficient to create a lifelong reputation for him.

Despite having had more work in television projects like The Lucy-Desi Comedy Hour and The Andy Griffith Show, Keith’s acting career was relatively short-lived, with the last role being on A Shadow in the Streets in 1975. He did return to the screen for a small role in C Me Dance in 2009. The now 70-year-old has had better consistency as a musician.
