Today Cybergraphix Animation announced the addition of Boo Boo Stewart (Seth Clearwater, Twilight Saga)  to the cast of the upcoming anime DVD feature Guardians of Luna. Boo Boo will play Jake Segerstrom alongside fellow Twilighter Kellan Lutz in the dark-action film, which will be completed in Fall 2011, and distributed by FUNimation Entertainment in North America.

Guardians of Luna centers around Carson Stone, who has come to Steelhenge looking for answers about his lineage. Driven by a mysterious letter from his father, what Carson uncovers is a city bearing an ancient curse. With each full moon, the city is terrorized by a pack of vicious werewolves. City leaders plan to eradicate the threat, and Carson must team up with three other werewolves in order to protect an ancient power source. In the process, they discover a dark secret about their ancestors that will force the “heroes” to make a crucial decision…on which could save humanity, or destroy it.
