If I adapt a copyrighted work, like writing a screenplay based on a novel, what rights do I have?

In Plain English

If you adapt a copyrighted work, such as turning a novel into a screenplay, you have the right to do the following, but only for your adaptation: * Reproduce it in a tangible form (write it down, type it, etc.). * Publish it (make it available to the public). * Perform it in public (e.g., stage the play). * Communicate it to the public (e.g., broadcast it).

However, remember that your right to do these things only extends to the adaptation you've created. You don't have the right to reproduce, publish, perform, or communicate the original novel itself, or to make other adaptations of it. Also, your right to do these things with your adaptation is dependent on you having permission from the original copyright holder.

Detailed Explanation

According to the Copyright Act 1968, Section 31 outlines the nature of copyright in original works. Specifically, subsection 31(1)(a) states that copyright in a literary, dramatic, or musical work includes the exclusive right:

To reproduce the work in a material form (31(1)(a)(i)).
To publish the work (31(1)(a)(ii)).
To perform the work in public (31(1)(a)(iii)).
To communicate the work to the public (31(1)(a)(iv)).
To make an adaptation of the work (31(1)(a)(vi)).
To do any of the above acts in relation to an adaptation of the work (31(1)(a)(vii)).

Therefore, if you create an adaptation, you have copyright over your adaptation. However, this is subject to the rights of the original copyright holder. You cannot exercise these rights without permission from the owner of the copyright in the original work.
