William Shakespeare's plays have a distinct ethical consciousness, and literary ethical criticism is of great importance to William Shakespeare. Therefore, when adapting Shakespeare's plays into the animated films, the ethical factor of the original works is an unavoidable part of the process. However, because of the differences in ethical attitudes between audiences of different times and the contradictions in ethical expression between different art forms, it is difficult to adapt Shakespeare's plays into animated films. In this paper, we believe that in order to eliminate the gap between time and space and make the ethical concepts in the original work acceptable to the contemporary audience, a kind of ethical "filter" is often necessary for the original work. In the animated films adapted from Shakespeare's plays, the "ethical filtering" of family ethics, love ethics, and violence ethics is especially important. It is only through such "filtering" that animation can be made more appropriate to the needs of the audience, and that it can achieve and perform its function of moral instruction for the particular audience.
