This has turned out to be a big day for casting news concerning comic book-based movies and TV series.  The latest news to drop is a report that four actresses are currently in the running to play the title role in the Marvel Comics-based Netflix series Jessica Jones.  With the Netflix Daredevil series already in production (see "First Look at Charlie Cox as Netflix’s Daredevil"), the casting of the Jessica Jones series can’t be far behind, and since Luke Cage will appear in 6-7 episodes of Jessica Jones, Melissa Rosenberg and the other producers at Netflix have to make a decision there as well.  Luke Cage will eventually get his own Netflix series, and after the completion of the four "individual" series (Daredevil, Jessica Jones, Iron Fist, & Luke Cage), the four heroes will combine in a final Netflix series that will complete "phase one" of the Marvel/Netflix experiment (see "Daredevil, Jessica Jones, Iron Fist, & Luke Cage Netflix Series").
 
Deadline is reporting that Alexandra Daddario, Krysten Ritter, Teresa Palmer, and Jessica De Grouw are all under consideration for the 13-episode Jessica Jones series about a superhero with post-traumatic stress disorder, who hangs up the spandex and opens a detective agency where her clients include other superheroes.
 
As for Luke Cage, the top two contenders for the role according to Deadline are Lance Gross (Crisis) and Mike Colter (The Good Wife, The Following).
