This fall, Johnny Depp rejoined his Pirates of the Caribbean director Gore Verbinski for Rango, which casts him in the role of household pet. (Yes, you can drool here, girls.) Last week, he was joined by Abigail Breslin, though her role was left unspecified. It was also unclear whether the film would be a combination of live action and stop-motion CG, or completely computer animated.

MTV got the scoop as to what we're in for -- and met a new castmember. The lovely Isla Fisher has joined the cast, and will be voicing a lizard that Depp's critter encounters on his travels. Ian Abercrombie and Hemky Madera have also joined the cast.

Fisher also revealed that the entire film will be filmed in a pretty unusual manner. The actors will film their performances, but rather than serving as the basis for motion capture, they'll merely serve as aide to the animators capturing their movements and facial expressions. It's something more elaborate than the usual camera-in-a-sound-booth approach that has been used for decades -- and really, might be some combination of motion capture and animation. Earlier, Verbinski described it as cutting-edge animation techniques that "will allow us to capture and translate every aspect of Johnny's performance, using it to drive the computer-generated character in a way that has yet to be seen in an animated feature." It's one to watch out for -- and we'll find out what they're talking about sometime in 2011, when Rango is set to be released.
