Screenplay vs. Novel
If you bundle up with a novel on a cold, winter night, a good author will take you into another world.
A fantasy world would come alive in words and images. It could be on a lush tropical island, a regular town, in the middle of vast desert or the blackest of space.
In the novel, the writer will use words to create a picture. You'll also receive the writer's observations and reactions about the environment and what's going on with the character.
In contrast, a screenplay is sight and sound, action and dialogue, with no extra comments or poetic techniques (unless found in character descriptions).
Your emotions and feelings are triggered by the actor's contribution to what the screenwriter lays down in the script. With screenplays, you have to know the basics of action and dialogue and how to keep the reader involved.
