The unity of action in Comedy of Errors is portrayed through a somewhat focused and well developed plot. The five acts in the play are devoted to one plot line and it development throughout those acts, catching the viewers entire attention, and giving the actors a primary focus as opposed to the latter which would be multiple plotlines tying together. Multiple plotlines are according to Aristotle are mere distractions, and this play does somewhat follow the guidelines he instates. More development can also be gained from a play with one main plot opposed to multiple plots assembled over the same amount of time.

The unity of place is also very key in the play though difficult to pull off. To only perform in one location is to exploit the location to the minds of the viewers giving them a developed feel for the location. The difficulties lie in maintaining the attention of the viewers when the play does not change locations, though it really depends on the play as well as how well it is portrayed.

The unity of time is a very delicate matter that depends upon how it is portrayed to the audience. A disadvantage to a short time frame is that it may seem hasty and it has the chance of confusing the audience. One could also argue that a shorter time frame would be simpler and more straight forward with the audience.
