When watching an actor on camera, a critic should always look at each actor within the context of the individual film, and the particular world presented on camera. If one was going to try to judge Johnny Depp’s performance in Edward Scissorhands compared to Tom Hanks in Castaway, it may be difficult if you didn’t understand the concept “context reviewing.” The worlds of Edward Scissorhands and Castaway are completely different. One feels more real to life while the other is exaggerated. But they both provide good acting within the worlds and stories in which they exist.
Tom Hanks performance here is called “naturalistic” (in acting terms) because his reactions and interactions are recognizable in our reality; in the world in which we all live; in how we can actually view life. Depp’s performance on the other hand is referred to as “non-naturalistic.” Director Tim Burton is known for creating unique, surrealistic, and distorted views of the world in his filmmaking style (set design, costumes, make up, hair, props, etc.), and many of his actors reflect that in their performances as well. It may be unusual to you, and feel different from your reality, but that doesn’t make it bad acting, it just makes it creatively unique.
Here is the key to evaluating the acting in a film – If an actor stays true (in physical appearance, facial expressions, speech, movement, and gestures) throughout a film, then one could say he/she has provided a clear illusion of believability. The actors have actually become the character (no matter the world) and have in essence become transparent and a part of that world we see on screen. As a critic that is what you want to look for, you want to believe that the character you are viewing actually does exist. If they make you feel they’ve existed within the story, they they’ve probably done a decent job acting.
