Hello my name is ***** ***** I will help you.
Have you copied anything, or just used the film to assist you in writing?
OK, then you dont need to worry. Unless you are copying the work you will be fine.
Look at the Wizard of Oz and the play Wicked.
Can I clarify anything for you about this today please?
Yes. Does that help?
All the very best.
Hello I am sorry but this answer is wrong and it is an extremely simplistic interpretation of copyright law as the expert has basically said is unless you are copying the work you are ok - highly misleading! There is a thing known as 'derivative work' in copyright law which deals with creating work derived or based on other people's copyrighted work. If there is a clear link between the two, then even if you had changed the names and tried to make it your own, if there is a link established, it could be a breach of copyright. This is something which is considered by juries in the courts but it is what they would look at so bear that in mind.
