Jackie Earle Haley
J.E.H. He was most famous as a child star for his role as “Kelly Leak” in the hit movie “The Bad News Bears.” Haley continued acting and has enjoyed even more success as an adult, earning an Oscar nomination for his role in the film “Little Children.”
Other notable roles include Rorschach in “Watchmen” and playing the re-imagined version of famous horror icon Freddy Krueger. He’s also appeared in the science-fiction film “Alita: Battle Angel,” which is based on a famous manga comic by Yukito Kishiro.
Brooke Shields
Shields's career started at five days old when her mother proclaimed, “she's the most beautiful child, and I'm going to help her with her career.” She played the part of a child prostitute in 1978's "Pretty Baby" and a dozen other films, including "The Blue Lagoon" and "Endless Love."
Shields seemed like she was on a path toward classic child-only stardom, but then she took a lead role in "Suddenly Susan," a sitcom that ran between "Seinfeld" and "ER." While the show itself never gained independent fame, Shields herself gained stardom. She's now a model, a mom, and a writer, having written the book "Down Came to the Rain," which detailed her personal struggle with postpartum depression.
Mike Lookinland
Lookinland appeared as the dark-haired youngest brother alongside Maureen McCormick on the "Brady Bunch." He tended to have smaller roles among his older co-stars, but he managed to have his moments despite that.
Lookinland also played parts in "Little House on the Prairie," the numerous "Brady Bunch" specials, and movies (most famously "Towering Inferno") before leaving show business. He's married, has two children, and owns a concrete business in Utah. It sounds like he's done the incredible – moved from child stardom to a simple, quiet life of family, work, and listening to the Grateful Dead.
Katy Kurtzman
Cast by Michael Landon to play Anna on "Little House on the Prairie" in 1977, Katy Kurtzman went on to star in "The New Adventures of Heidi" as the titular role, which has garnered her the most fame. Kurtzman continued acting, appearing in the hit show "Dynasty" in the 1980s. Katy later moved into writing and directing and wrote a short called "The Pool Boy," which she directed back in 2001.
Her most recent acting role was in 2013 when she made a guest appearance on the TV show "Grey's Anatomy."
Scott Baio
An award-winning young star, you're likely to remember Baio from "Happy Days." But he was also one of the title characters on the spin-off "Joanie Loves Chachi," as well as the lead character in "Charles in Charge." He also had a key supporting role in "Diagnosis Murder." Baio has also had plenty of movie credits, including "Baby Talk," "Perry Mason: The Case of the Fatal Fashion," and "Very Mean Men."
Baio's daughter Bailey has been diagnosed with a rare metabolic disorder and a meningioma brain tumor, the first of which prompted Baio to found the Bailey Baio Angel Foundation.
