In the early scenes, when Freddie Beenstock's father is eyeballing Jim Heeler and Henry Hobson, through his window, on their way to Moonraker's Pub, the "Beenstock & Sons" lettering is painted on the middle panes of the colonial type windows and are aligned with Mr. Beenstock's chest and waist. Just a few frames later, when Freddie joins him, the lettering has moved to the top panes and is aligned with their heads.
In the scene at the beginning of the film when Hobson is at the bottom of the staircase, the shot shows a mat or carpet at the top of the stairs. Hobson runs up the stairs and the shot showing him saluting at the top landing, shows no mat or carpet at all. Only a bare floor.
