Zoe Kazan confirmed for Allen's muse in JLA

Moviehole say they have talked to actress Zoe Kazan who was able to confirm she has been cast as Iris Allen in the JUSTICE LEAGUE OF AMERICA. Allen is of course Barry Allen's (a.k.a. The Flash) other half. I have been unable to find Kazan's age but she is a Los Angeles native and her career is really just getting stared in the industry. She had a small role in FRACTURE this year and also IN THE VALLEY OF ELAH and next year will be seen in Sam Mendes movie REVOLUTIONARY ROAD. She actually has third billing in that movie, above Kathy Bates and Michael Shannon, easily her biggest role to date. I wouldn't expect her part to be that big in JLA though, probably just playing off a few scenes with Adam Brody, who is all but confirmed as The Flash. Warner Brothers are still keeping very quiet on this. Are they embarrassed by the cast they have sewn together?
