The Master

When Lancaster Dodd is challenged by a skeptic, the shadow of a boom microphone is visible on the wall behind Dodd.

The architectural style of the house where they stay in Philadelphia is known as California craftsman, which is not found anywhere in or near Philadelphia.

In the "pacing" scene, as Quell goes from wooden paneled wall to window and back, the second time he goes to he wooden paneling, he breaks out a panel when he pounds it with rage.

In the numerous successive shots, the wood panel is restored.

Although some of the nurses in the hospital scenes could have been at a V.

, the doctors could not.

The V.

is not staffed by military, and the doctors do not wear military uniforms.

When Freddie is first seen visiting Doris' house, aluminum stick-on numbers are visible in the establishing shot, giving a street number.

These numbers didn't' come onto the market until the 1960's- long after the time when the scene takes place.

When Freddie starts undergoing processing at Helen's house, Lancaster Dodd has a handkerchief in his left hand but as the camera switches to a different angle, the handkerchief has shifted to his right hand.

When Freddie smashes the toilet in his jail cell (at about 1;17), no water spills onto the floor, showing that the prop toilet was completely dry.

When Freddie is taking portrait photos in the department store he pulls out a Readyload or Quickload sheet from the back of the camera.

These film storage technologies weren't developed until well after WW2.
