On the duplicate entry's Overview page, go to the "Report" button (is in the same row as the "Discussions", "Reviews", "Videos", "Images", "Changes", etc. buttons), click on it, a Report screen will open, check off "Duplicate", then indicate, in the message field, what it's a duplicate of. Posting the link to the entry that it duplicates will prove helpful to whichever moderator responds.

Only a moderator can remove a duplicate movie, show, celebrity listing, etc.

Thank you very much!

Thanks for that too. I'm just learning, making a few mistakes. But Enjoying the results of those that work out. :)
