All this, and Black Canary has made it to live-action television as well!
Birds of Prey
Sadly, the show couldn't seem to find an audience...after all, who would want to watch a series set in Gotham without Batman?
Rachel Skarsten did well after, going back and finishing high school and college before coming back to acting on series like Flashpoint and the L.A. Complex, and movies like the Vow. Most recently, Rachel has been a regular on the series Lost Girl about the Fae (beings of supernatural origin) split into light and dark factions, and fought by Bo (series star Anna Silk), who refuses to choose a side. Rachel plays Tamsin, a Dark Fae, who joined the cast in season 3, as a partner to Dyson (Light Fae werewolf cop, one of Bo's lovers, played by Kris Holden-Reid), and helped turn Bo's life upside down (but has been more help in the fourth season....and more!).
Alaina Huffman continues to work steadily to this day...taking on a permanent role as blond Lt. Tamara Johansen on SGU Stargate Universe (that lasted from 2009 to 2011, wherein a Stargate took a military crew and some civilians to a ship far across the universe, but without the power to return home). Alaina is currently working on Supernatural as red-headed Abaddon, one of the demons faced by the two brothers (Sam and Dean Winchester, played by Jared Padalecki and Jensen Ackles) who hunt demons on the CW show.
Lauren became a lawyer while Ollie was gone, and losing Sara also helped to break up the Lance family (though Dinah Lance, Laurel's mom, did come back thinking Sara was still alive....and was played by Alex Kingston).
While Laurel was in the action here and there, mostly she just caused complications for Ollie (and was sleeping with his best friend, Tommy Merlyn, played by Colin Donnell).
Laurel then suffered some more tragedy as well...
With Sara leaving the city, she gave Laurel the Canary jacket (and likely...the identity of Canary for season 3!).
Caity Lotz played Officer Kirsten Landry on the MTV series Death Valley (and faced all sorts of supernatural threats...) in 2011.
Caity was also a part of Don Draper's past as Stephanie on Mad Men. Part of the reason she was so graceful as the Canary is her history as a dancer!
Katie Cassidy is a very happy lady, enjoying her time on Arrow. Previous long running roles of hers include Ruby on Supernatural, Ella Simms on Melrose Place and Juliet Sharp on Gossip Girl.
Katie also runs a fashionista blog, Tomboy KC and she's looking forward to seeing more action with Arrow Season 3 (aren't we all?).
Heaven help Ollie if these pretty birds flock around him (though it would make the fans very happy!).
