I thought major stars are supposed to be listed as cast members in movies.
Natasha Richardson provides the voice for one of the two main characters in The Wildest Dream: The Conquest of Everest.
She is the love interest for the main character, George Mallory who is played by Conrad Anker and voiced by Ralph Fiennes.
Fiennes is listed as a cast member but Richardson isn't.
Other voice actors are listed, Hugh Dancy and Alan Rickman, as well as Liam Neeson as the Narrator.
So why is Richardson left out. I can understand Anker as well as Leo Houlding since this is the only movie they have done as characters, thought they have both been in 7 and 6 movies or TV episodes respectively as themselves since they specialize in documentary broadcasts.
But Richardson is an actress and just as involved in this movie as the other three actors and equally billed in all posters, etc.
