Not exactly a springboard to fame
Something really strange about this show is the lack of modern stars it produced. Ryan Reynolds is the only member of the cast who's had a successful post-Fifteen career. Out of all the different people who appeared on the show only seven are even famous enough to have a head shot! If I had to pick another success I might say Laura Harris, who was a regular cast member on season two of 24. I didn't really recognize it was her until she spoke to her family from prison.
Being inconsistent is better than being consistently bad.
