Anyone that knows anything about acting will tell you that "stage" actors are always better seasoned and trained than "strictly screen" actors. Al Pacino said doing stage is like walking on a tight rope high in the air without a safety net, while doing movies is like walking on a line drawn on the floor. Which one do you think is more difficult?

Further more, great stage actors can, and usually do, very well in movies. While many, many screen actors, who have never done stage, don't do so well when they try stage. The camera, or director cannot hide a poor performance when you are doing stage.
