Dementia 13

It gets off to a fast start. It's night. A couple decides to go out in a row boat. The husband is rowing. The wife tells him to take it easy---he's got a bad heart. He suggests that her concern is only because, if he dies before his wealthy mother does, she will inherit nothing. A second after he says this, he clutches his chest.

"Now you've done it!" his wife scolds.

She starts rowing them back to shore.

"If I die, you get nothing!" he warns her seconds before he dies.

She tosses his body overboard, writes a letter to her mother-in-law signing her husband's name and she goes to their estate pretending that he's still alive, as if no one would figure this out if she tried to inherit the family fortune.

And there's a serial ax murderer.

I've seen microphones bobbing around at the top of the picture in movies before, but this movie did it in combination with clear distinct shadow of the boom mic on the actors. Which may have been good because I would have guessed that the sound was dubbed.

It was pretty good. I don't know what the title meant, but that was good, too.

Reportedly, it was shot in the UK the same time as Roger Corman's The Terror and another movie. They had time to shoot one more movie before they returned to Hollywood, so Corman had a little contest---his own Project Greenlight. It was between Francis Ford Coppola and the Israeli Menahem Golan. They each wrote a treatment for a movie and Coppola won.

Dementia 13 is public domain and available on various Roku channels.

Coppola had been the soundman on another Corman movie. Watching the dailies, Corman told them he could hear the camera noise on the soundtrack. It was Coppola's fault, be he talked fast and blamed the cameraman. Corman knew he was lying, but was impressed at how well he could think on his feet.
