whats defference between screenplay & script?

Answer 1

A script has the lines that the actors say.

A screenplay has everything from the script, but it also has everything that happens on the screen such as camera directions, shots etc.

Fade in on open sky, pan down slowly past tops of trees to reveal a house in suburbia. A crash is heard.

And on and on for at least 100 pages.

Answer 2

generally, there isn't. still, there's a nuance. when you write your own, original work, it'd be called 'script' (it's what they call it in Hollywood 'unsolicited script' or 'spec script' -- meaning one written on the speculative hope that you would sell it)
or, if you are a pro and a studio assigns you to write a script from an existing story/concept/book/play/movie/script, then it is called 'screenplay'.
that's why on the screen credits you often will see 'written by', meaning it's an original script, and 'screenplay by', meaning the script is based on an existing piece.

Answer 3

well a screen play is when you write the basic story or idea and a script is when you write what your characters do and say.
