The Diegetic gaze [3rd person]- The joker (2019) allows the viewers to sympathize for the character, to come down to their level. For this scene, coming down to this position helps us connect with him a lot more because were are too, being placed on the floor.
Intra-Diegetic gaze [first person]- Paranormal Activity (2007) using what’s called “found footage” in films are among the most popular sub-genres of horror movies.

Extra-Diegetic gaze- Nightcrawler (2014) uses a subtle forth wall break. Unlike movies like Deadpool and American Psycho which talk directly to the camera, Nightcrawler uses a scene where the character Lou Bloom looks directly into the camera for a second.
