Year range Heathcliff
Currently, Heathcliff has a year range of 1980-1984: https://www.imdb.com/title/tt0173556/reference/
However, as you can see, all episodes on IMDb are from 1980-1981.
TVmaze also says this series ran from 1980-1981: https://www.tvmaze.com/shows/46528/heathcliff
So does epguides.com: https://epguides.com/Heathcliff/
Can a staffer look into this and fix the year range please?

Hi, @Marco:
I've noticed that you've recently reported several cases similar to this one, involving completed series that ended later than the year of the last episode listed on IMDb. Just out of curiosity (and if you feel like continuing to investigate and report similar errors), I've cross-referenced the data from title.basics.tsv, title.episode.tsv and title.releases.tsv to see how many series have discrepancies in the dates.
As of 14 May 2026 18:24h, there are on IMDb:
Obviously, I’m not going to post the list of over 13,000 titles here (if anyone’s interested, I can send it to them), also because I suspect that many of those discrepancies are series with correct start and end dates, but whose final episodes haven’t been added to IMDb (it’s understandable that a contributor might upload the first few episodes and then not follow through on completing all the seasons).
That's why I've put together a selection of interesting data that I think is worth looking into:
🟩 YEAR OF THE EARLIEST EPISODE PRECEDES THE START YEAR OF THE SERIES 🟩
➡️ 402 series ⬅️ [sorted by gap between series vs episode years]

🟨 YEAR OF THE LATEST EPISODE IS LOWER THAN THE END YEAR OF THE SERIES 🟨
➡️ 10,481 series ⬅️ [sorted by gap between series vs episode years]
I hope you find these listings useful.
Cheers! 😊
