Ant Bully: According to Variety, Warner Bros. and Playtone have set Julia Roberts to top its vocal cast for Ant Bully, the CGI animated film written and being directed by Jimmy Neutron: Boy Genius helmer John Davis.

Roberts will voice a CGI ant named Hova. Also in the colony are Shirley MacLaine, Paul Giamatti, Alan Cumming, Cheri Oteri and Ricardo Montalban. Playtone partners Tom Hanks and Gary Goetzman are producing with Davis and his DNA Prods.

Ant Bully is based on the illustrated children's book by John Nickle about a mischievous boy who menaces an ant colony and destroys its anthill with his water gun. He's shrunk to insect size and sentenced to hard labor in the colony. Newcomer Zach Tyler will voice the shrunken kid, Lucas Nickle.
