When Guiding Light airs its final episode today, it won't just be the end of a remarkable television success story -- one that has endured on radio and TV for 72 years -- it will also lower the curtain on some of the most memorable characters ever. In the past 25 years that I've been watching Guiding Light, I've had the pleasure of watching the likes of Michael Zaslow, Justin Deas, Michelle Forbes and Kim Zimmer portray some of those characters.

So, in honor of what Guiding Light has achieved, the fabulous writers who have created these stories and characters, and in salute of all the wonderful actors who've brought them to life, here's Guiding Light's 10 greatest characters from the past 25 years.

10. Josh Lewis (played by Robert Newman)
With the creation of Joshua, the Lewis family became a foundation in Springfield, as integral as the Bauers and the Spauldings, and Josh was the key. He started as a young, upstart oilman with a romantic streak and over time has morphed from a business tycoon to a minister. And through all the years, he's had one great love, Reva Shayne.

On February 29, 2008, a new era began for Guiding Light. Daytime television's longest running serial drama -- 71 years old this year -- burst out of the confines of a New York studio to begin shooting on location and on the fly in makeshift, portable sets and real places. The idea on paper was not only exciting, it seemed revolutionary. If they succeeded, Guiding Light could truly be a "guiding light" to the rest of the soap industry.

Mysterious. Mesmerizing. Interesting. Dynamic. Compelling. Any and all of these words accurately describe actress Michelle Forbes. She is one of the finest actresses in television, and yet she has maintained a distinct quality that makes her as elusive a performer to come around since Garbo! Intensely private, there's not much known about the Austin, Texas native. (However, I can tell you that she collects clocks -- broken clocks. As she told me, quoting the movie Withnail and I, "Even a stopped clock tells the right time twice a day.")

She's currently making HBO's new drama In Treatment appointment TV, drawing her loyal following to find her latest work as she did in 24, Prison Break, Homicide and Battlestar Galactica. And that doesn't even take into account the millions who first discovered this chameleon when she first burst onto the scene in Guiding Light, and then Star Trek: The Next Generation.
