It's hard to believe Casey Affleck turns the big 3-8 this week, just four days before his latest film, "Ain't Them Body Saints," hits theaters. It feels like we've watched the youngest Affleck grow up right before our very eyes. His first big-screen role came in "To Die For" (1995), opposite future bro-in-law Joaquin Phoenix. And then there are his collaborations with the elder Affleck, Ben, in films like "Chasing Amy" (1997), "Good Will Hunting" (1997) and "Gone Baby Gone" (2007).

Both of the talented Affleck boys have each enjoyed successful careers after getting into the business when they were just kids. Lucky for Casey, he never had to live in the shadow of his big brother, proving his talent was all his own after scoring an Academy Award nomination for his role in "The Assassination of Jesse James by the Coward Robert Ford" (2007).

Fancy awards and A-list siblings aside, though, what is a career in Hollywood if you can't make a name for yourself in the game of Six Degrees of Kevin Bacon? Good thing, then, that Casey can stake his claim to fame by saying his very first gig at 13 years old was opposite the man, the myth, the legend that is ... Kevin Bacon.

That's right. An adorable Casey Affleck bonded with Bacon during his acting debut on the PBS series, "American Playhouse." Casey kicked off his career playing a 12-and-a-half year-old (almost 13!) in the episode, "Lemon Sky."  Helping a headache-ridden Bacon feel better with some aspirin, and even schooling him on how many pills to take, the two partake in a nice boy-to-man chat. It seems that everything about Casey's mannerisms — including his voice and sly smile — don't seem to have changed all that much in the last 25 years.

Check him out back in 1988.
