Directed by: Juan Carlos Fresnadillo

Continuity mistake: When the plane lands at the airport, it is a Boeing 737 without winglets. When it taxis to the apron in the next shot, it is a Boeing 757. Then again it is a 737 with winglets, then without and finally with them.
Factual error: The route the children take to their house on the moped doesn't make sense - this is just to show the London landmarks.
Question: If the infected can sense the uninfected due to the uninfected smelling clean and scented (deodorant/perfume), wouldn't the closest approximation be to just stop bathing or showering, and not wearing deodorants/perfumes? Wouldn't one rather be dirty than dead? Am I over-simplifying the situation? Do the infected sense the uninfected using some other method in conjunction with the above, thereby nullifying my hypothesis above?
Answer: I suspect that it's really not that simple. Remember that in the first film, Jim was lying alone in a hospital bed for some considerable time before waking to the deserted London. He would certainly not have smelt clean and fresh, yet he was still clearly detectable as prey by the infected. While being nice and clean makes it easy for them, it seems clear that it's not the sole indicator that triggers an attack.
