So for the past few days I’ve been noticing more and more of this film. Any ideas?

Looks like a heavy amount of bio-film perhaps...? Looks like it to me. And if it is, best solution is to get some shrimp, otos, clean up crew. That stuff is always all over my tubing. It's harmless, but isn't particularly cosmetically attractive to look at it at all.
Or...it could be young/preliminary BBA. (black beard algae) Or green hair algae. Yeah, I'd highly recommend a bunch of Amano shrimp to clean up that BBA/bio-film.
