Factual error: Laura gets in the elevator to find Rich; she tells him on the phone there are 12 lower levels to choose from (that is, 12 basement floors to choose from) - but there are only 6 buttons in total on the control pad. (00:23:15)
Factual error: When Rich and Laura are checking the US Patent Office records for the Nortide drug, the date of the patent is shown as "December 22th, 1963." The form is a modern, barcoded typed document, not a hand-written or typed one, and supposedly a formal US government document, so the '22th' should not have happened. (00:15:45)
Factual error: When Rich and Laura are searching for drug information from the 1960s, they visit the US Patent Office website; under the heading "SSRIs", is displayed "Selecttive Serotonin Reuptake Inhibitors" - with the double-t spelling error. (00:15:25)
