Other mistake: After the decontamination chamber scene, Bond and Honey drink a cup of tea. Honey very quickly passes out due to the tea being laced with some type of sleep inducing drug. However, as Bond throws his cup in anger, Honey flinches very hard. Surprising considering how quickly she passed out after drinking the tea.
Other mistake: At the beginning of the film when the lady who is calling London on the radio is shot through the glass there is a jump cut. This shows that two scenes were spliced together. Perhaps the prop gun didn't work the first time. The framing of the shot noticeably jumps when the gun shot happens.
Other mistake: At the end, James and Honey jump into a small boat, and after James has dealt with the two men in the boat, Honey deals with the front tender, but no-one deals with the rear tender - we can see it rising out of the water, but somehow it is no longer attached to the boat.
