Continuity mistake: When M is imprisoned and is being spoken to by Robert Carlyle she is wearing a multi-coloured scarf which is draped over her left shoulder and down the left side of her body. When Carlyle leaves the room M turns around and walks towards the bed. The camera angle is reversed and she's not wearing the scarf. Later it is shown lying across the bed.
Continuity mistake: Despite running and jumping for her life, traveling at over 70mph, tumbling head over heels, and several massive explosions (during the nuclear factory and pipeline sequences), Dr. Jones' hair remains pinned up in a French twist with nary a strand out of place. Uh-huh. This is particularly glaring considering near the end of the film, the impact of an explosion finally does knock her hair loose.
