If you're not afraid of the dark now, you just might be after seeing 'Vanishing on 7th Street.' The new post-apocalyptic thriller by director Brad Anderson ('The Machinist') stars Hayden Christensen, Thandie Newton, John Leguizamo and newcomer Jacob Latimore as a group of survivors trying to figure out how to sustain themselves in a world where everyone has inexplicably vanished.

The movie doesn't have a traditional villain. An ambiguous "dark" entity engulfs anyone who doesn't have his or her own source of light, whether it be from a flashlight, a candle, a lighter, a glowstick, or exposure to the ever-shrinking bursts of daylight. The four survivors take refuge in a bar that's powered by a back-up generator, but the sinister shadows are never far away.

'Vanishing' had its world premiere as part of the Toronto International Film Festival's Midnight Madness line-up. We caught up with Christensen and Newton the following day at the Windsor Arms Hotel, where a crowd of onlookers lurked outside trying to catch a glimpse of the stars.
