At one point - there were three ways to tell if it was a Criterion title vs regular Filmstruck title: 1) the cover image had a wacky C on it, (2) - it was on the Criterion channel, and (3) - when played, it opened with either a Janus or Criterion logo.
One and two are easy enough to find out - but has anyone checked with the third option regularly? I ask - because When a Woman Ascends the Stairs seems (in the above image) - like it would've been skipped under some of the above criteria. Thats fine when its an already released title we know about - but what about something more obscure? I'm not asking that someone checks every single non-Criterion branded title to find if something were missed - but if someone with an account (or working access to the website) could see if some suspect films begin with Janus / Criterion logos.
I know that even some films with Criterion branding don't even have the Janus / Criterion logo start (I think I remember someone saying the Bunuel Robinson Crusoe did/does that - so unless they've since gotten their act together, it seems like it could be complicated. I'm sure they don't want to give away as to everything they own / have licensed anyway.
I check now and then for Janus / Criterion logos - last one was The Best Intentions during the Bergman drop (no Janus or Criterion logo).
Robinson Crusoe also has the C logo faux cover - left shows as a search result, and the right shows when you click on it's page.
