She does have a point. No one called Andy Serkins a "voice actor" in LOTR, or King Kong, or Planet of the Apes series. If you go to a studio, move your body for motion capture and lend your voice, then in my book you are an actor. Why differentiate between Theater, TV or Video Games? We all know video games now make more money than movies. The people that play character more or less all went to acting school. Where is the difference?
