I've been writing a YA mystery book in which one of the three main characters is a detective—who now seems to share his name with another fictional character on TV.
I was pretty young when I came up for the idea for the characters, and wasn't really aware that there was another fictional character out there with the same name, let alone that he was on a fairly popular show. (Found out when I saw commercials that repeatedly used the name!)
My character has nothing to do with the one on TV; besides the name they only share the characteristics of both being white and male.
I really like that name anyways, since it fits my character so well.
If I tried to publish this someday, would I run into copyright/legal issues, even though my character is nothing like the one on TV? Would I therefore need to change his name?
Edit: the name itself is somewhat uncommon, but it's really just two fairly common names together. The first name is just Harvey, but put that with the last name and you get a character on a popular show (I only withhold it to save myself the embarrassment of having it on the Internet forever :) )
