Then: Korsmo was kind of a big deal in the early '90s. The wide-eyed child actor played prominent roles in ‘Dick Tracy’ and ‘What About Bob?,’ in addition to his turn as Jack Banning in ‘Hook.’ After a seven year break from acting, Korsmo returned for his final role as loveable geek William Lichter in the 1998 teen comedy ‘Can’t Hardly Wait.'

Now: It turns out Korsmo is quite the brainiac in real-life, too. In 2002, he received a degree in physics from MIT and followed that up with a degree from Yale Law School in 2006. Currently he's a professor of corporate law at Case Western Reserve University in Cleveland.
