Here is one for those who enjoy the "disappearing person" thriller, most recently seen in Flightplan and, with an unusual supernatural twist, The Forgotten. The progenitor was probably The Lady Vanishes, and another good one is Dangerous Crossing.

Bunny Lake Is Missing is Otto Preminger's take on the story. Unlike most of these others, which sets the action in an isolated location, this takes place in London. Okay, so a little girl can disappear in a big city any number of ways, but how can the desperate mother account for all the people who swear they never saw her? Preminger, who even directed straight dramas with all the energy of suspense thrillers, is in his element here. This film is creepy, haunting, and a whole lot of fun.
