Robert Blake had one of the longest acting careers. He began acting as a child in 1939 in the movie “Bridal Suite” which starred Annabella and Robert Young and after being drafted into the army, he proceeded to become a seasoned Hollywood actor.
He enjoyed a long career in Hollywood until 2001 when he had to quit the business after he was accused of murdering his wife, Bonnie Lee Bakley. Blake was acquitted for the murder and has since maintained a low profile.
Dylan and Cole Sprouse
The twin child stars, Dylan and Cole Sprouse were made successful Disney stars after starring in "The Suite Life of Zack and Cody." After the Disney channel rejected a series they pitched, the two decided that it was time to call it quits and they proceeded to pursue degrees at NYU.
Dylan has since opened a bar in Brooklyn, and as for Cole, he actually returned to television in 2017, acting as Jughead Jones in CW's "Riverdale." He is also set to return to the big screen, starring in 2019's Five Feet Apart.
Elizabeth Hurley
More commonly known as Liz Hurley, the actress is best known for acting as Vanessa Kensington in "Austin Powers: International Man of Mystery" and as the Devil in "Bedazzled."
Hurley has since retired from acting to focus on raising her son, while remaining out of the spotlight.
Ariana Richards
You might remember Ariana Richards for her role as Lex Murphy in none other than Steven Spielberg's 1993, "Jurassic Park." Ariana had appearances in various television programs throughout the 90s and early 2000's, like "The Golden Girls," "Empty Nest" and "Boy Meet World."
However, her acting career did not continue on to adulthood and the child star retired in order to pursue her passion as a painter.
Macaulay Culkin
There is perhaps no more of an iconic child star than Macaulay Culkin was. By age 12, he became the most successful child actor of all time. He is, of course, best known for playing Kevin in the Christmas movie "Home Alone" and "Home Alone 2." With a promising career like his, it was surprising to see him retire at age 14.
Perhaps this had to do with his estrangement from his father. While he has appeared in some things here and there, he has mostly chosen to stay out of the spotlight.
