When Nancy Voorhees Townsend is at the newsstand and picks up the Evening Gazette with her photo from 20 years ago beside the photo of the man she killed back then on the front page, the headline above the two photos is "Nancy Voorhees Story". But after she walks away with it to pay for it, another copy with the same two photos on the front is shown at the newsstand, but with the headline "2 Die in Subway Cave-in". After she pays for the one in her hand, that's loosely folded in half, part of the headline on it can be seen, and it isn't "Nancy Voorhees Story" as it had been - it's now the "2 Die in Subway Cave-in" headline. That same 'subway' headline is in the next shot when she sits down at the desk at her apartment to read it, before she hurriedly hides it in the drawer when her daughter enters the room.

Randall (Edward G. Robinson) is finished pointing at Isopod (Boris Karloff), who departs, and tells the blonde to "Get me that address." Then he places his left index upon his lips and starts pondering. His right hand is supporting his bent left arm. The picture cuts to the next frame in a long shot where Randall looks at his secretary, and he is now in reverse position, his right hand upon his lips and his left hand in his pocket.

As they finish the bridge game, Mr. Voorhees is sitting at the table totaling points. Cut to quick shot of the engaged couple on the sofa, then a quick cut to phone ringing, and Mr. Voorhees is standing right by it, even though it's across the room from his seat at the bridge table.

Though clearly done for artistic reasons to keep the film fast-paced, several times people are relaying information from a phone call too fast. In other words, they aren't allowing time for the person on the other end of the line a chance to tell the information that is supposedly being relayed. This is especially obvious when Randall gets the update on Nancy (complete with address) in less than a second.

In the 1931 newspaper photo of Nancy Voorhees during her trial 20 years earlier, she is wearing 1931 clothes, not 1911 clothes, as she should have been.
