Meet The Cast Of 'Eclipse'

Huston and Moreno, who was last seen in 2008's two-part Steven Soderbergh epic, "Che," are the latest additions to an ever-expanding cast. Summit Entertainment made headlines last month when they announced the controversial decision to replace [article id="1617156"]Rachelle Lefevre with Bryce Dallas Howard[/article] as Victoria, a vampire hell-bent on getting revenge on Edward and his human paramour Bella for killing her partner, James.

The David Slade-directed "Eclipse" is set to be released next June. Chris Weitz's installment, "New Moon," the second film in the series, will hit theaters on November 20. A leaked [article id="1618586"]French trailer for "New Moon"[/article] that made the Internet rounds on Wednesday showed the first glimpse of Dakota Fanning as Volturi guard member Jane, but it's since been taken down.
