Goofs

When Cargan and Max force Magee back into the house; Magee takes off his coat and holds it on his right arm. But on the very next cut when Magee is asked where he is going; Magee is now holding the coat on his left arm.

When Magee and Jordan discover the body in the secret passageway, the shadows on the wall are not right for the light source they are using.

When Pete the Hermit gives Magee the money; Magee tells him to go get the police. Pete then asks if he was sure about giving him the typewriter; Magee answers that he will give him two of them. But Magee never did offer him a typewriter therefore the dialog doesn't make any sense.
