The Gore Verbinski - Johnny Depp reunion project Rango has already gotten some attention this week with the news that Abigail Breslin joined the cast. It looks like that cast has gotten even bigger, with Isla Fisher (Definitely, Maybe) coming aboard.

The news comes from MTV’s Movies Blog, who got to talk to Fisher during a junket for her upcoming film, Confessions of a Shopaholic. Fisher announced that she would be playing opposite Depp in the movie as the voice of a lizard Depp’s character encounters on his adventure as a household pet who… well, winds up on an adventure.

Fisher also talked about the process Verbinski is using to make the animated movie, which includes having the actors actually act out the scenes to aid the animators in portraying movement and expression. That’s not uncommon for animated movies, but Fisher seems to indicate Verbinski’s approach is a bit more elaborate, according to MTV.
