Blooper

The captain, who regains consciousness after being hit by Gilbert and holds the remaining passengers at gunpoint, suddenly disappears from the story.

When the manager comes into Gilbert's room in response to the complaint of noise, Gilbert is playing his clarinet. He removes it from his mouth, and yet another note is played.

Two or three shots after Miss Froy writes her name on the window, the writing is not only different but also in a different place.

Iris is wears a dark scarf with her initials on it until she faints after stopping the train. It is gone in the next scene: replaced by a large pin on her dress.

Just after the train starts out, it is on a high bridge. Behind the locomotive and tender are a van, four passenger cars, and another van. Just after the lady vanishes, an exterior view along the side of the train shows at least five passenger cars, and it is stated that there have been no stops.

In Europe, the hotel manager says it is "spring" when talking about the avalanches. However, the two English travelers are trying to get back to England for the Manchester cricket test, which was always played in July.

When the young lady is standing up and pulls the emergency cord to stop the train, she remains in a stable upright position. A sudden stop by a train should have caused her to lose her balance and be flung in the forward direction of the train.

In the noisy dancing scene above Lockwood's hotel room, the clarinet is shown with the mouthpiece turned with the reed upwards. Normally the mouthpiece is turned so that the reed is downwards, but in some European folk traditions the clarinet was played with the mouthpiece "upside-down".

There is no explanation of why there is a grand piano in the office of a civil servant.

There is no rule that office décor be justified; there could be many reasons for the piano to be in an office. It's left to the viewer to use their imagination.

Set in winter, yet when Miss Froy stands at the hotel window to admire the moon and stars, there is a tree branch with thick full living leaves above her head.

Mrs. Froy writes her name in the dust on the inside of the train window. Later, when the train goes through the tunnel, the name is erased by the locomotive's black smoke--from the outside.

In the opening scene, the camera tracks downward in an aerial view over the side of a snow-covered mountain to show railroad tracks and the front of a train's locomotive buried by an avalanche, close to a train station in a small mountain village. As the camera passes over the train and four railroad officials standing to the left of it, one of the officials swivels to the left and then to the right, as if he were rotating on a pivot. As the camera moves closer to the ground, away from the train station and along a village street at ordinary eye level, it shows an automobile crossing the far end of a street; the string pulling the automobile along the street is plainly visible for an instant. Both this detail and the movement of the railroad official show that the entire opening scene was shot upon a scale-model miniature set.

The newspaper which the cricket fans were reading was the New York Herald from March 17th, 1938, the day after the inaugural NIT final between Temple and Colorado. The cricket match which they were trying to get back to England to watch was played in July of that same year.

(at around 10 mins) When the maid reaches down under the bed to get her hat, Charters opens his mouth with a gasp. Then, as he and Caldicott turn around, something drops into the bucket of water. However, during the aforementioned events, the sound is muted. The sound returns once the maid stands up with the hat.

The train scenes were filmed in England, where trains ride on the left track. In continental Europe (except most of France), where the story is supposed to take place, trains ride on the right track.

At one point "Mrs. Todhunter" says that her husband thinks she is on a cruise, so she is concealing her adultery; later she says that she told her husband, on leaving him, that he would never see her again.

When the man from the Foreign Office tells Gilbert and Iris that they can be seen now; the man turns his back and they proceed to follow him toward the office door. Suddenly, Gilbert stops Iris and then tells her to wait a minute. However, the man anticipated the "wait a minute" line and stops to turn around before Gilbert says the line.

Gilbert had plenty of time to write the music down. If anything had happened to him, Iris could have still delivered the message.
