Use of close up- Digetic
My example of an effective use of this is a scene from Avengers: Age of Ultron where the very last form of Ultron is standing opposite his failed vision. This close up is used to show how weak and destroyed ultron is, to show that he has lost and he is truly powerless. During this scene Ultron and Vision have an almost father son conversation about themselves and humanity as a whole, and serves to make us almost feel bad for ultrons demise, while ultron is portrayed through all of it as weak and fragile vision is portrayed with powe, the close ups help with this as it makes it more personal as even though he is robotic his body language and voice are displayed to add emotion and impact to what he says.
Intra-diegetic –
The opening scene in Spider man homecoming is a first person montage of peter documenting his day where he is given his new suit etc. This montage is used to show how excited peter is and how keen he is to be helping and doing something good, this scene makes peter feel more relatable as he acts how any teenager who has been given super powers would act, overall this scene is great for portraying and building the character of peter Parker in the fan favorite way.
Extra-diegetic
In the film – Deadpool 2, the main character of deadpool constantly breaks the fourth wall and speaks to the audience, this is done for not only comedic purposes but is also a specific character trait of deadpool. Comedy is however definitely the main focus as deadpool constantly makes jokes referencing pop culture and previous films in the same cinematic universe which allows more devoted fans to almost feel some kind of recognition from the character of deadpool as some of the things he says will only be understood by people who have extensive knowledge of both the comic source material and the other films,
