* Commercial Success: The biggest former child star in terms of commercial success would likely be Macaulay Culkin, who rose to fame in the early 1990s with the "Home Alone" film series. The first two "Home Alone" films were critically and commercially successful, and Culkin's portrayal of Kevin McCallister became iconic. He also went on to star in other successful films such as "My Girl" (1991), "The Good Son" (1993), and "Richie Rich" (1994). However, Culkin's career declined in the late 1990s and early 2000s, and he has since had limited success in the entertainment industry.
* Critical Acclaim: The biggest former child star in terms of critical acclaim would likely be Jodie Foster, who began acting at a young age and received widespread recognition for her performances in films such as "Taxi Driver" (1976), "The Accused" (1988), and "The Silence of the Lambs" (1991). Foster has won two Academy Awards, three Golden Globe Awards, and a BAFTA Award, among many other accolades. She has successfully transitioned to adult roles and continues to be a respected and acclaimed actress.
* Longevity: The biggest former child star in terms of longevity would likely be Leonardo DiCaprio, who rose to fame in the 1990s with films such as "What's Eating Gilbert Grape" (1993) and "Titanic" (1997). DiCaprio has continued to be a successful actor in adulthood, starring in critically and commercially successful films such as "The Departed" (2006), "Inception" (2010), and "The Wolf of Wall Street" (2013). He has won an Academy Award, three Golden Globe Awards, and a BAFTA Award, and is considered one of the most successful actors of all time.
* Cultural Impact: The biggest former child star in terms of cultural impact would be difficult to determine, as different individuals have left a lasting impression on popular culture in their own ways. Some contenders could include Michael Jackson, who rose to fame as a child with the Jackson 5 and later became one of the most influential and iconic musicians of all time; or Elvis Presley, who began his career as a teenager and became known as the "King of Rock and Roll", significantly shaping the music industry and popular culture.
