When I watch movies, the first thing that grabs my attention is the Continuity Mistakes in those movies. I wonder when exactly the filmmakers would have noticed the Continuity Mistakes and learned about them. It is not a sin but it is better for filmmakers to consciously keep that in their mind and avoid it. Pinpointing the very first movie with a continuity mistake is challenging due to the limited documentation and historical records, especially from the early years of world cinema. However, as the industry developed, filmmakers became more aware of continuity, and mistakes were noticed.
Film Grammar VS Cricket
If there is a comparison of Cinema Grammar and Language with Cricket Matches, the following can be an option;
Art House Movies - Test Match
Commercial Movies - One Day Match
Anime Movies - Twenty 20 Match.
Art house movies take time to explain the cinema language. Each character, plot, situation, and drama unfolded slowly and steadily. Due to the pace of the movie, everything takes time to settle down and most importantly, the end is predictable. This is like a classical language which needs a special understanding of the language. Fans of this kind of movie often blame the other two pace of cinema languages. As people call Test Match the purest form of Cricket, Art House fans too claim that this is the purest form of filmmaking. They criticize Commercial and Anime Movies as a Junk and waste of time.
