According to Wikipedia, Chris Rock will voice “Fox” and “Snake,” while Andy Richter will take on “Bird” in Disney’s upcoming American Dog. If this news proves true, then the duo will join John Travolta, Thomas Haden Church and Mario Cantone for the 2008 CGI adventure. Meanwhile, the site also has the latest word on Paramount Pictures/Nickelodeon Movies’ The Smurfs. Rumor has it that James Horner will provided the movie’s musical score, with Colin Brady (Everyone’s Hero) and Norton Virgen (The Rugrats Movie, Rugrats Go Wild!) directing the feature.
