Other mistake: People 'sleeping' in the hibernation pods are lying down under force of gravity, connected by their left hand fingers to sensors monitoring them, they're not strapped in or clamped down in any way. So when the gravity was lost for 5+ mins they would have lifted inside the pod, hit the top, probably disconnected from the left hand sensors, and maybe dropped back down awkwardly out of place for a future arm injection. Maybe even triggered an early wake-up procedure of the pod, as perfect equilibrium would be disrupted by getting no data from the sensors.
Other mistake: During the party at Max's house there is no black out despite an air raid going on. Light spills out of the house into the garden.
Other mistake: When Jack confesses to Bridget that he lied to Mark, there is a landline telephone on the table beside her. When Bridget goes into labour and Mark throws away his mobile, they wonder how they will phone for a taxi, ignoring the landline.
Other mistake: The navy bombardment opens fire and there are huge explosions. When they attack from the ropes they walk at least 50 yards with no craters, just flame and smoke. Awfully big guns for no holes in the ground .
Other mistake: The typewriter ribbon in Gemma Arterton's typewriter looks to be installed upside down, with the red half of the ribbon showing above the black half.
