Deadpool(2016 , directed by Tim Miller) is a great example of the Extra  digetic  gaze being used effectively because it is used for comedic impact and in that regard , the technique is incredibly effective and it helps to include us in the inner world of the character. Furthermore ,Deadpool is the only Character to break the fourth wall and this adds to the comedic effect of the film.

This scene from The Man from U.N.C.L.E(2015 , directed by Guy Ritchie)  uses digetic perspective to put emphasis on the main character Napoleon Solo – this conveys the fact that he is a pivotal character within the narrative as the focus is on him specifically and all of the other people in the frame are  out of focus and blurry and this lets the audience know that they are unimportant.

This Scene from The Good , The Bad and the Ugly(1966 , directed by Sergio Leone ) famously utilizes the intra digetic gaze – the two opponents are glaring at each other and they have a tense stand -off and the gaze helps to build up the tension within the scene  and it tells the audience that the two characters absolutely despise each other.
