As with many DC Comics adaptations before it, the upcoming Supergirl TV series has already confirmed a number of comic book characters, such as Hank Henshaw (David Harewood), Jimmy Olsen (Mehcad Brooks), Alura Zor-El (Laura Benanti) and many more. TV Line reports that CBS is currently seeking actresses to play Lucy Lane, the sister of Lois Lane who is also known as Superwoman. The network is seeking actreses in their mid-20s to early 30, with Lucy described as "brash, funny and beautiful as her sister Lois, yet strong, smart and successful in her own right."

The show will follow DC Comics lore, with Lucy being an ex-girlfriend of Jimmy Olsen's. It was made quite clear in the first Supergirl trailer that Melissa Benoist's Kara Zor-El develops an instant crush on Jimmy Olsen, with TV Line speculating that a love triangle of some sort could ensue between Kara, Lucy and Jimmy. Whoever lands the Lucy Lane/Superwoman part will have a recurring role on the series, although it isn't clear how many episodes she will appear in, or if there will be an option for her to become a series regular, if the show is picked up for a second season.

Superwoman was last portrayed on the small screen by Peyton List in Smallville, but it isn't known how this new character will differ from the previous incarnation. Supergirl recently added another DC Comics character to the show, Maxwell Lord, played by Peter Facinelli, but we're not sure how many other comic book superheroes will be popping up in the first season. It isn't known if whoever is cast to play Lucy Lane will actually transform into Superwoman in Supergirl. In the comics, she was just one of several characters who became Superwoman. She was also manipulated into becoming a villain for Supergirl by her father, General Sam Lane. But it isn't known if that character will be appearing on the show. The previously-released trailers have also teased that Kara's cousin Superman will at least be referenced and established as a superhero on the show, but it remains to be seen if he will actually show up or not.

There have also been rumors that Supergirl could cross over with The CW shows Arrow and The Flash, since all three shows are produced by Greg Berlanti and Andrew Kreisberg. CBS has shot down rumors of a crossover, but Greg Berlanti was recently pictured on a Variety cover with both Melissa Benoist and The Flash star Grant Gustin. Naturally, this doesn't exactly confirm that a crossover is happening by any means, but we'll have to see how Supergirl fares when it debuts on CBS this fall.

Dean Cain, Helen Slater, Calista Flockhart, Jeremy Jordan and Chyler Leigh also star in Supergirl, debuting Monday, October 26 at 8:30 PM ET. The show will then move to its regular time slot at 8 PM on Monday, November 2 for the remainder of Season 1. What other comic book characters would you like to see on Supergirl this season?
