Erik Von Detten, the voice talent behind characters on ABC's animated series ``Recess'' and ``Toy Story,'' has been added to the cast of Disney's ``Princess Diaries.'' The picture, helmed by Garry Marshall and produced by Whitney Houston, Debra Martin Chase and Mario Iscovich, tells the tale of a rebellious young girl (played by Anne Hathaway) who discovers she is the princess of a small European country. Von Detten's TV credits include a series regular role on ABC's defunct ``Odd Man Out'' and the Disney Channel's ``So Weird.''
