"I did do some child acting," Affleck admitted, adding that he's thankful he didn't find more success early on. "Luckily, I didn't end up on a show, and get famous, and go on crack, and get crazy."
"It was a PBS series called The Voyage of the Mimi," he revealed, when host Jimmy Fallon pulled a clip from the 1984 television program, where a young Affleck was completely adorable, and had a bit more of a Boston accent than he does now!
ET actually spoke to the 42-year-old actor about The Voyage of Mimi at a recent junket for his new film, The Accountant, where he shared that his children -- 10-year-old Violet, 7-year-old Seraphina, and 4-year-old Samuel -- haven't seen his kid actor debut, namely because if it's not Taylor Swift, "they are so not interested."
Additionally, Affleck said he doesn't discuss his early role with his children mostly because he doesn't want "them to get any ideas" and start acting themselves.
