I would like to have this show duplicate movies using custom field 8 which is the IMDB link. I suspect that this might be searching another field as I know I have some duplicates (some with The in front and some without) but was waiting for this implementation before I started cleaning. Unfortunately it doesn't find them
Spiral and The Spiral both have an IMDB link of
http://akas.imdb.com/title/tt0491162
but it does not detect as duplicate. Thanks in advance and thanks for implementing more duplicate finders for us!
