Factual error: When Blanc goes through the possible methods of death in a locked room mystery in "The Hollow Man," the first two are not actually the ones listed in the novel, since they refer to a complete accident and a trap set up inside the room that causes a fatal accident, respectively. And when Geraldine comes up with the solution, she tells Blanc that it was the "fourth" one while it would be the seventh.
Factual error: It's not stated in the movie, but "L'EVEIL APPEL" does not mean "the evil apple" or "Eve's apple" or anything of the sort, but rather "Call to awakening", which fits the movie and theme (and the presence of a Jesus figure instead of a tree, apple, etc.). However, it's not really proper French (it should have been "appel à l'éveil"), which is quite odd for a Fabergé container worth 20,000 $.
Factual error: Throughout the movie, Cyrus constantly records, keeping his phone vertical, but his videos are perfect landscape mode recordings (except for the one of Father Jud and Monsignor Wick's argument).
Factual error: Lee Ross's book signing happens a year after the murders. Since dates are very precise, we know those happened in 2025; therefore, the signing should be in 2026. But his book signing is on "Tuesday, April 1st." April 1st in 2026 is on a Wednesday. It was on a Tuesday in 2025, so they just picked the wrong date for that one.
Factual error: The killer meets Doctor Nat around 11 PM. According to the police station clock, Father Jud turns himself in around half past 2 AM. By the time the body is discovered, it has been barely 4 hours, and its flesh has been thoroughly consumed by a bathtub of acid. No acid corrodes a still intact body this thoroughly in such a short time and without any further action.
