Acting is showcased in a theatrical aspect as well. Hamlet adopts a role of insanity in order to mask his plotting endeavors. Professional performers have to be able to mimic a wide variety of mental states; this could demonstrate just how committed Hamlet is to the execution of his revenge. Moreover, the Murder of Gonzago set-up acts as a ruse which forces the king to understand just how despicable his actions have been. The idea of a play-within-a-play reminds the audience it is subject to the realistic and manipulative nature of drama.
It can be observed that acting in Hamlet is used to deepen the receptive effect and character intricacies. The same is true of any other play and life in general. It is as Shakespeare writes: "All the world's a stage." People even today act in calculated ways so as to obtain desirable results and to hide parts of their true identity.
