For the best part of 10 years, Kiefer Sutherland captured the hearts of many audiences around the world with his portrayal of the gritty counter-terrorist agent Jack Bauer.
While Kiefer/Jack was the focal point of the show, he couldn't save the day alone and got help from all kinds of places. Whether it was folks in the White House, the staff at CTU or maybe a few villains who had a change of heart, the long running series was not short of a few memorable (or unmemorable) characters.
Fans of the series will know who Jack Bauer, Chloe O'Brien and Tony Almeida are, but around them were characters who came and went. Even so, looking back now, it's rather fun to see so many big stars who had such small roles in the series when it first aired. There are plenty of "oh! it's him!" or "wow, they were on the show once?" moments that accompany a rewatch today.
With that in mind, let's take a stroll down memory lane and revisit some characters who stayed with us forever, and others who were a flash in the pan.
