Animation and CGI

A very interesting question, and one that I cannot answer with any real certainty. I suspect that it depends on the actor or actress in question and how versatile that person is. All the great animated films have still required actors to produce the voices. I realise that this is not absolutely necessary because a person can emulate a voice without the need of acting ability, but famous actors and actresses have contributed to many of the great animated characters. I suppose a lot may also depend on the type of acting role that a person usually plays. For example, there would be far less demand for a Shakespearean actor.

No, i don't think it would have negative impact on actors. CGI offers new experiences in watching movies, but still the actor have to give a believable acting skill, because no matter how good the CGI is, if the actors can't act, then no one will watch the movie.
