Eric Morris is an American acting teacher and actor who founded his own theory of acting based on the works of Lee Strasberg and Martin Landau. Morris lives with his wife in Los Angeles and teaches actors the Eric Morris System of Acting.

Having published over five books in his theory, Morris claims that his method is derived partly from Lee Strasberg's Method Acting. However, Strasberg's Method focuses too much on craft, according to Morris, and not enough on the actor's instrument. Facing struggle in finding truth, he contemplated his theory while heading the Directors Unit at the Actor's Studio in Los Angeles. Morris' method recognizes the fact that actors have emotional blocks, tension, insecurities and other preventions to achieving a fundamental state of being, and works to clear these blocks, rendering the actor truly organic. In this sense, Morris stresses that acting is essentially living and being. There are seven major obligations to material, according to Eric: 1) Time and Place, 2) Relationship, 3) Emotional Obligation, 4) Character Obligation, 5) Historic Obligation, 6) Thematic Obligation, 7) Directorial Obligation. After recognizing these 7 obligations, there are the choices the actor utilizes to render these emotions, and finally the approach to which the actors use these choices.

The Eric Morris System has received praise from such actors as Jack Nicholson and Johnny Depp.
