A screenwriter or a screenplay writer, or a scriptwriter or scenarist is a writer who practices screenwriting and writing screenplays as a craft on which mass media such as films, comics, and drama, television programs, or video games are based.
The screenwriter works often independently. He holds the responsibility of finding a story and developing the narrative, besides writing the script, after that delivering it to the executors.
The screenwriter can make a great emotional impact on the script and the film. He explains his ideas to the producers, so they buy or adopt them, on the other hand, the producer may ask the screenwriter to write a script about a real story, a novel, a play, a comic book or short story to be turned into a movie.
The script is highly based on the dialogue, if the dialogue is not strong enough or literally weak, then the script is weak, so, the screenwriter must use a good form of dialogue that enhances the power of the image.
The experts have agreed on ten basic conditions for a successful script, one of these experts is Professor David F. Howard, M.F.A, who mentioned these conditions in his famous book “the tools of screenwriting” which is considered to be the writer’s guide to the craft, these 10 conditions are:
- The dialogue should reflect and express the speaking character.
- The dialogue should be characterized with special phrases which add a feature for the speaker and are related to the script.
- The dialogue should reflect the character and express its feelings.
- The dialogue should expose the personal motives or any attempts by the character to hide these motives.
- The dialogue should reflect the relation of the speaker with the others.
- The dialogue should be related to all previous dialogues and conversations, or any previous acts, so it is sequential and leads to new dialogues and acts as the script moves forward.
- The dialogue should contribute in developing the character’s acts.
- The dialogue should contain information or certain attitude sometimes.
- The dialogue should imply incoming acts and events.
- The dialogue should be clear and practical.
