Avengers: Age of Ultron Casting Call Seemingly Spoils Plot Point

Ever wonder how Ultron comes into being without the involvement of Hank Pym? Well, according to Feature Film Casting, it won't be much of a secret--at least to anyone trying out for a part in the movie, which begins shooting in the U.K. in February. Exactly how credible the casting notice is, though, might be a question mark. Here's how the industry website describes the film:

Marvel Studios and The Walt Disney Studios are now in pre-production on the upcoming sci-fi themed superhero feature film "The Avengers: Age of Ultron", and casting directors are auditioning actors for starring, co-starring, and supporting roles. The film's photo doubles and stand-ins for the starring actors, as well as general extras and featured background actors will be cast closer to the start of filming. The locations where outdoor principal photography will take place are in and around London, England. Indoor sound stage filming will take place at Shepperton Studios. Shooting begins in February, 2014. In "The Avengers: Age of Ultron" Loki is gone and the new villain will be the evil robot Ultron, who has the ability to keep upgrading his own strength, making him extremely fearsome. Tony Stark/Iron Man becomes the unwitting creator of Ultron. The brother-and-sister team of Quicksilver and the Scarlet Witch become the seventh and eighth members of The Avengers. Quicksilver has extreme speed, while Scarlet Witch can cast spells and has telekinesis ability. Black Widow and Hawkeye will be key figures in the film.

Of course, it seems unlikely that this is an official synopsis; there's a lot here that seems like it's just rephrased from recent news stories about the film, and the absence of Loki seems an unnecessary inclusion for an official document to make. It could be, then, that this is merely an employee at the casting website making a few intuitive leaps in the hopes of providing what they feel is an insightful and helpful description of the film for those who hope to audition.
