I noticed that IMDB has two separate entries for Jo Helton of the Dr. Kildare show and a bunch of other TV appearances in the 1960’s, and Jo Wintker, who has a small part in Dumb and Dumber To (but a prominent role in the trailer - she is the old lady who claims to be hiding something with her under the sheets of her bed).
This is actually the same actress - in fact her most recent credit in the Helton entry notes her credited “as Jo Wintker.” How would one bring this to IMDB’s attention so the entries can be merged?
