When Condomine has writer's block, his typewriter is an office machine with the type-bars in a cylinder formation. When Elvira is helping, days later, it is a semi-portable with the bars in a cone.

A one point there is a wide shot of the phone ringing but when there is a direct cut to a close up view, the receiver has been reversed in the cradle of the phone.

Early on, Condomine puts a record on an acoustic gramophone and puts the needle down to the left of the spindle, where it would dig into the record if it would play at all. (The image has not been reversed because the record is still turning clockwise.)

Part way through, a telephone call is made, and the receiving phone is heard ringing. It rings with the American single ring, yet this move is placed in England, so it should be the English double ring.

During the opening scenes of the movie, displayed is the 4th June 1937 morning issue of the Daily Herald newspaper with the headline that reads DUKE OF WINDSOR MARRIES WALLIS SIMPSON IN FRANCE, and that marriage took place on the 3rd of June 1937. Their house hosts an Aga in the kitchen, which was not released by the Aga Rangemaster Company until 1939.

The shot of the entrance to the Savoy shows it flying the post-1965 Canadian flag.

When Charles and Ruth are in the kitchen (when Ruth burns her hand on the scorched casserole dish, which she had just removed from the oven), feeling a bit amorous, Ruth suggests they move their davenport beds back together. This was a moot suggestion, as previously, the twin beds had already been pushed back together.
