Screenwriting Step 5

Screenwriting literature.

I have read some screenwriting literature and i would say that it helped me alot if i had read it before reading existing screenplays but i can only say it helped me slightly as it gave alot of information on the format of how a screenplay is produced like when to use INT & EXT, Location and timing which i already learnt from reading existing screenplays as i read the existing screenplays i realised as each scene changed it would give the information on where they are and what time it is but obviously formated as i just explained.
Screenwriting literature gives information on how to format a script when a certain charecter makes a certain action and when editing should be input which i again already learnt from reading existing screenplays.
Although reading screenwriting literature i obviously more helpful then reading existing screenplays because with reading existing screenplays i had too realise the patterns to know how its formatted but with the literature it just straight up tells me what to do really simply therefore i thought that reading screenwriting literature is helpful.
I also learned alot of different genre element from reading screenwriting literature for example it said that if you are doing a screenplay with an action genre then it should be fast moving quite alot of the time and always going, obviously you dont have too write the screenplay without and sort of sitting down, talking moments but it cant bore someone for too long as it is an action movie but you can still give a narrative base towards it but you dont have to go too much into detail with the narrative were as with a horror movie it has to be sneaky and tense and the narrative base of the screenplay has to be clear and put across well.
There is information on most genres with was the most helpful for me in my personal opinion, there was alot of other elements that was really helpful aswell such as structure and introduction but i already knew about them before reading some of this literature but i didnt read all of the literature, i only read a few segmants and the amount of information i got out of it was phenominal and it makes me think about ordering my own screenwriting book to help me with the screenwriting unit as i already know how helpful they are just from reading a small amount.
