Summit Lands Denali Clan for ‘Twilight’ Sequel ‘Breaking Dawn’

MyAnna Buring, Mia Maestro, Casey LaBow and Christian Camargo will be joining the fanged franchise

"The Descent" star MyAnna Buring has joined the cast of Summit's "Breaking Dawn," along with Mia Maestro ("Alias"), Casey LaBow and Christian Camargo ("Dexter"), the studio has confirmed to TheWrap.

Buring, LaBow and Maggie Grace join the fanged franchise as a trio of Russian vampire sisters who belong to the Denali coven. Buring will play Tanya, who rivals Kristen Stewart's Bella for the attention of Edward (Robert Pattinson). Grace has already been cast as the villainous Irinia, while LaBow will play Kate, who has the ability to produce an electric current that can shock her enemies.

Maestro and Camargo will respectively play Carmen and Eleazar, the Spanish heads of the Denali coven, the only other vampire clan besides the Cullens who don't feed on human blood.

Bill Condon is directing the two-part "Twilight" sequel, which is set to begin production in November.

The first film will be released on Nov. 18, 2011, while the series' denouement will arrive in theaters on Nov. 16, 2012.

The Denali clan's casting was first reported by the Hollywood Reporter.
