Some of the voice cast for Zack Snyder’s animated film based on Kathryn Lansky’s children’s book Guardians of Ga’Hoole has been announced in tonight’s edition of THR. The supporting voice cast includes Jim Sturgess (21), Geoffrey Rush (Pirates of the Caribbean), Rachael Taylor (Transformers) and David Wenham (300).

It has been rumored that Hugh Jackman, Hugo Weaving and Ryan Kwanten (True Blood) will make-up the voice cast lead roles, but that has yet to be officially confirmed.
The animated film is an adaptation of the 14 book bestselling kids series by author Kathryn Lasky and illustrator Richard Cowdry (the film is based on the first three books in the series). The producers have described the tone as more “Harry Potter” “than Happy Feet.” The story follows a young barn owl named Soren, who is kidnapped by owls of St. Aggie’s,where owlets are brainwashed into becoming soldiers. He and his new friends escape to the island of Ga’Hoole, to assist its noble, wise owls who fight the army being created by the wicked rulers of St. Aggie’s.

Guardians of Ga’Hoole is scheduled to hit theaters on July 30th 2010.
