A friend of mine and I often role-play using characters from various movies and books in stories and settings of our own imagining. Sort of like verbal fan fiction . One of the characters I particularly liked playing has inspired me to make a similar (but far more developed and complex) character in a book I'm writing. And now the problem: my friend (who has a bit of a stake in the book I'm writing) has gotten so attached to the name of the character which inspired my character that he doesn't want to let me pick a new name! The characters are roughly similar in appearance, temperament, and profession, so I'm afraid that, should my book ever get published, readers will say, "Ha, you lifted your character from ___!" With a change of name, the original source of inspiration would be very difficult to pinpoint. I've already voiced these concerns to my friend, but he remains adamant that I should not pick a new name. What else can I tell him to change his mind?
