When rumors become pervasive, it's difficult to know whether each new clue is a "real" clue or just a restating of existing rumor.
Such is the case with the latest issue of CineSaga, a French film magazine, which reportedly gives away the identities of three as-yet-unconfirmed roles in Batman V Superman: Dawn of Justice, stating matter-of-factly that the actors are playing the characters they're most commonly rumored to play.
Comic Book Movie got their hands on a copy of the magazine, which names Jena Malone as Barbara Gordon, Callan Mulvey as Anatoli Knyazev, the KGBeast, and Scoot McNairy as Jimmy Olsen.
If true, this will mean yet another Arrow character has made his way to the big screen (Knyazev), following in the footsteps of Deadshot, Katana, and Amanda Waller -- two of whom have been killed on the series since. Knyazev has been a relatively minor player on Arrow, so it's likely he would simply not return if it's true that the movies really are what's driving those character deaths.
The page scanned by CBM has no new information about what the roles would entail from what I can tell. Although my memory of high school French is fairly limited, it appears these are just bios of the actors, not their characters.
The piece also claims there's a flashback sequence featuring The Joker, which isn't much of a leap given the prevalence of Jason Todd's defaced Robin costume in the trailers.
Take all of this with a grain of salt, of course; the magazine doesn't cite a specific source for the casting announcements, as far as we can tell.
The movie is out in just over a month, though, so information should start coming soon...!
