Goofs

Latimer's fiancee has a latchkey to his flat in some scenes but not others.

At 1 hour 15 min as the fight moves into a second room three pictures hang perfectly on the wall. After the fight moves beyond the door one picture is now askew.

At 1 hour 15 min Henson hits Latimer with a chair who then falls to the floor unconscious. When Latimer first appears on the floor there is no debris around his head. In future scenes various pieces of the chair are on the floor around his head and shoulders.

Near the start, when Windsor drives Latimer to the airport, it is dark, but later Brady shows Latimer a photograph of him (Latimer) at the airport with Windsor and the shot was taken in daylight.

At 1 hour 15 min during the fight between Latimer and Henson punches are thrown/landed and glass breaks that does not match the actions of the fighters.

The shadow of the cameraman is thrown in front of him as he shoots the villain's arrival at London Airport.

When doctors Latimer and Kimber leave the West Brompton hospital the camera crew is visible for a fraction of a second in the glass entrance door as it swings back on itself.

Latimer lives in Ennismore Garden Mews, which does not have an Inigo Jones church across the road from his front door as shown several times (some of those images are clearly painted backdrops).

Charles Kaufmann, Latimer's friend with a distinctive US accent, telephones him four times. On each occasion Howard - oddly - has to ask who he is speaking with, despite later admitting he believed the first three calls were genuine.

Howard Latimer doesn't seem to pause and wonder why Palmer owns a record featuring music with loudly-overlaid party atmospherics. (He may believe it was planted in the flat by the murderer.)

Kaufmann phones Latimer asking him to collect Frieda Veldon from London Airport on the 3:15 flight from Berlin. Putting the receiver down, Latimer tells Windsor he's to meet her at 6pm - but no such arrival time was stated.

At the end of the film, Howard's friend Kaufman has him paged at an airport phone, but there is no way he could have known that is where Howard was.
