Before Leonardo DiCaprio boarded the 'Titanic,' and before he became a recurring star in Martin Scorsese's films, he starred in the 1995 film 'The Basketball Diaries.' An adaptation of the book of the same name by Jim Carroll, the film follows a teen, Carroll (DiCaprio), as he slides deeper into the depths of an alarming drug addiction. The film also starred Mark Wahlberg long before he became a beloved action star. Eighteen years later, we revisit DiCaprio, Wahlberg and the rest of the cast and see what they're up to now.

Then: Former Calvin Klein underwear model and rapper Mark Wahlberg (aka Marky Mark) starred as Jim's friend, Mickey. This was only Wahlberg's third film role, and it would still be two years before he landed the part that made him a huge star -- Dirk Diggler in 'Boogie Nights.'
