Page "Voice acting" Paragraph 11

Some voice actors, such as Billy West, are highly critical of using movie stars for voices in animated features.

A particular point of contention is the practice of bringing in veteran voice actors ( who are generally capable of greatly altering their voices and inflections in order to create personalities for characters ) to read for a part, and then use the recording of the professional voice actor as a guide for the movie star, even though the actual character creation work is being done by the unpaid voice actor.

West struck back at this practice in Comic Book: The Movie, in which the entire main cast comprises voice actors, including Jess Harnell, Lori Alan, Daran Norris, Mark Hamill and Tom Kenny.

The practice of hiring singers to " fill in " for voice actors in a singing role has also seen change, as both Jeremy Irons and Mel Gibson have done singing in the respective films The Lion King and Pocahontas, rather than have a singer as substitute ( However, the former did most of his own singing, but due to straining his vocal cords, he didn't finish ; instead, Jim Cummings did his partial singing voice for the rest of the song ).
