Eeeerrrm ... Just remember that not all people were looking for RP names during the charater creation process.
Just because a charater has a name inspired by a movie or book doesnt mean the person had any thoughts further than "a name ... Gee, this may sound nice. Hrrrm, its taken. Ill just change a letter ... ".
Just like how I had no RP thoughts or inspiration when I thought "name? Yes, a breakfast cereal will make a good sounding charater name ..."
But I agree with ripping off entire charaters, but you cant assume someone is ripping off an entire charater based on what the player chose to name it.
