Green Lantern, The Flash and Talia al Ghul Revealed
DC Comics fans have been on the edge of their seats for the last few days waiting for some official casting for the upcoming Justice League film, for now here is the Flash, the Green Lantern and Talia al Ghul.
A few months ago the IESB brought you the news that both Justin Long and Adam Brody had been brought in to read for the role of the Flash, a few days later the Trades confirmed our scoop.
Today I received a phone call from a source who has some pretty close ties to people involved in the production and gave us a tidbit, Wally West/The Flash will be played by Adam Brody.
By the time that I received the tip, it was too late in the day to reach the anybody from the studio for comment, we had been hearing similar rumblings for the last few days but no confirmation from anybody at WB at this time.
The other name we are hearing was pretty much locked as of a couple of weeks ago was Common as John Stewart/The Green Lantern. We confirmed this with multiple sources.
Also, remember those rumors that claimed that Teresa Palmer has been cast as Wonder Woman? Not true, Ms. Palmer has not been cast as Princess Diana, our sources are telling us that she has been cast as Talia al Ghul, daughter of Ra’s al Ghul.
One thing is for certain, actors have been sworn to secrecy and have been warned not to reveal their involvement even to their closest friends and relatives.
One studio source, who has been asked not to be mentioned by name, told the IESB that several actors that starting talking early on were warned by the production that they could lose the role if they revealed their character or even the fact that they had been cast.
We have our ears to the ground in Texas this weekend for Wizard World. There have been rumors for a good part of a month that announcements were being planned by WB during the Con. We have checked with couple people over at Wizard and they have not been able to confirm or deny if anything is planned this weekend.
Stay tuned as we bring you Justice League news as it breaks.[/quote]

Scoop: Scott Porter Is JLA's Superman!

Scoop: Scott Porter Is JLA's Superman! It looks like the dam is about to burst on the casting of Warner Bros. Justice League of America movie. It’s just unfortunate that it had to happen late at night on a weekend, when I’m full of Scotch and in no mood to talk about which Hollywood actor will be abusing his crotch with tights next.
Anyway, here’s the skinny. Tonight we got an email from a guy claiming to be in the know with what’s going on in the JLA camp. He asked to remain anonymous, but he says he knows at least part of who is playing who. Normally I’d just delete such an email out of hand, after all we’re all sick of fake JLA rumors by now, but some of what he said confirmed heretofore unknown production tidbits I’d already heard from others, and then about an hour after he sent the email to me, another site posted a story confirming at least part of his casting rumor… yet they appear to have gotten their info from a completely different source, since their cast list doesn’t contain the real gem of the bunch… Superman.
So here’s the deal. Our source says Warner Brothers is set to announce the completed JLA cast next week, and Scott Porter (that’s him to your right) has been hired to play Superman. If you’ve noticed Porter at all before now, it’s probably as a regular on the TV series Friday Night Lights. He also had a fairly significant part in Music & Lyrics, and he’s just finished filming on Speed Racer as the brother of Racer X, Rex Racer.
He’s 29, from Omaha Nebraska, and about as all-American looking as a guy can get. I guess that’s what you want in a Superman, isn’t it? Now can the guy act? Wait, this is JLA. Who cares. Can the guy convincingly carry the Statue of Liberty over his head? That’s all that matters.
In addition to Porter, our source says Common is now signed to play John Stewart/Green Lantern. Adam Brody has been added to the cast, probably as The Flash. Teresa Palmer is on board but not as Wonder Woman. Other sources suggest she’s playing the daughter of Batman villain Ra’s al Ghul, Talia Ghul. Last, Michael Gough may make an appearance as Alfred, after being kicked out of the part by Michael Caine in Chris Nolan’s Begins movie.
So that’s the latest, and we've been able to confirm a lot of it with several different methods. Maybe this time we have a JLA cast rumor which is reliable. Everyone seems to agree WB will make an official announcement next week, so we won’t have long to wait for the final, full, cast list. We still don’t know who’s landed major parts like Wonder Woman or The Martian Manhunter.[/align][/spoil]
