Joe Scaramanger was telling me how he reckons one of the reasons Hollywood is doing so many remakes and "period" films and stuff is because mobile 'phones enable the protagonists to call for help very easily, so you need to get them into a situation where either they haven't got one, or that the one they have doesn't work.
