If I was to make a series of something and followed my own storyline for the majority of it. If I was to do one part of it (I'll say episode, I can't think what else to call it) that was based on something made by another person, should I say that?

Say if I actually had the means to actually make my series an actual series on TV (farfectched, I know) and one episode was directly based on a movie or a book or something that I didn't write, but I felt like paying homage to for one episode, what do I do - do I credit myself for writing the episode like normal, and then say it's "based on a story by (whoever wrote the book or movie)"?

Just curious. Move to whatever forum.
