Although TBH they sold it somewhat like a horror movie, and apparently it's not (maybe the meh Cinemascore is related to this, haven't seen it myself).
DISCLOSURE DAY nabbed $19 million on Friday for a likely over/under $45M domestic debut. Unless I missed one, that’s the 2nd-biggest opening weekend for a non-horror *original* (all respect to world war movies), behind F1 ($57M) last June, since SAN ANDREAS ($54M) in June 2015.
