In one of the first scenes, the shifting heard is that of a close-ratio gearbox. In the rest of the film, the shift pattern heard is that of a conventional gearbox.
When Marianne Faithful approaches the French customs border for the second time one sees the same clip of the customs official and the beige Fiat 850 that was used the first time she approached the border.
At the beginning of the film, Rebecca is naked when she goes to the cupboard for her leathers, but when she puts them on she is suddenly wearing knickers.
When Rebecca & Daniel are staring at each other in the ski lodge, actor Alain Delon is holding a whiskey tumbler.
When Rebecca is still looking at the glass after he's gone, it changes to a brandy snifter.
When Rebecca first visits the barn where she keeps her motorcycle, the side stand is on the left which inclines the bike in that direction. She approaches the bike from the left and mounts it. This is the correct side (as with mounting a horse). Many other occurrences, the motorcycle is standing upright and she mounts from the right riding off without retracting the stand. Clearly on a dolly or trailer.
In close shots Rebecca and her motorbike stay vertical even going around corners, revealing the fact that she was probably on a trailer being towed behind the camera.
Virtually at the end of the film after Rebecca has crashed, a British roadworks sign is seen, yet that scene is meant to be set in Germany, which uses a different style of roadworks sign, showing that scene was made in the UK.
In the close up of Alain Delon teaching Marianne Faithful to drive a motorbike with him seated behind her, her fringe hardly moves despite the rush of air.
Towards the end, as she's counting down the distance to Heidelberg. She is suddenly wearing her crash helmet in some distance shots but is bare-headed in close up shots.
The bike she rides is a Harley-Davidson. Throughout the film the soundtrack lacks the distinctive H-D sound; in fact, if you listen closely it becomes quite obvious that the sound dubbed was that of a British twin motorcycle of the era (either a Triumph, BSA or Norton).
After she avoids colliding with the lorry the shadow of the camera is momentarily visible as the motorbike takes a bend.
Marianne Faithful apparently leaves the cafe without paying for the cherry brandies she had been drinking.
