I guess to know the whole truth, we’ll have to wait and see. Straight from the get-go, though, it seems like TPTB might be puppets for a force, or entity(?). The fact that they gave us a few avenues for numerological assessment is telling, though.
DISCLOSURE (10 letters) can be compressed to 1 (via 10→1+0), and DAY (3 letters) to 3, giving you a 1–3 pattern. Thirteen is literally 1 before 3 (ahavah + echad = 13), often read as death‑to‑old‑self and birth‑to‑spirit. It could also be referencing talking heads: three behind the one, a plurality behind the one. We only see the one, or spearhead. Plus, 13 is representative of the masculine Sun, which is the centre of the 12 feminine zodiac. 12 is also representative of the Moon, because the moon undergoes 12 lunar cycles. Masons and the like venerate the sun, and have been doing so since Nimrod/Gilgamesh.
Breaking down the release date, we see;
June 12, 2026 (06/12/26) reduces to 6–3–8 (12→3, 26→8): 6 as sinful humanity, 3 as divine fullness, 8 as new‑cycle / resurrection (the opening Saturnian square opens at 7–8 years of life), so the release date encodes a humanity/fullness dynamic, birthing a new loop. On another note, the possessed meteorologist is a human “mouth” hijacked by a higher power on a mass signal—probably referring to influential people whose words are not really their own.
As noted by another commenter, the crosses, nun, etc, suggest the old church‑shell being re‑used as a stage for a new, idolatrous, “god,” vaguely reminiscent of Revelations and other pieces of apocalyptic literature.
Finally, given that this movie will be centred around the idea of aliens, one close event evoking the same feeling is 3I ATLAS. On the 19th of December, 3I ATLAS will be at its most visible. Breaking the name down, we get: “3I” = triadic creation plus the I/eye; “ATLAS” = bearer of the sky and the world‑map, plus the neck of the body. The third eye, or Ajna, symbolizes spiritual awakening, so if 3IATLAS is a thing, it’ll probably involve much more than meets the eye.
P.S. I’m probably reaching here (if not just plain wrong), but it’s definitely an interesting thought worth humouring.
