We'll be treading in the footsteps of Coppola, Stone and Kubrick as we journey into the heart of darkness with our very own Vietnam-based movie.

In one of our craziest challenges yet, the presenters will be trying to travel the length of the Socialist Republic of Vietnam in just eight days. As you'd expect, our movie involves rather less theologising about man's inhumanity to man and the futility of war, and quite a lot more mucking about with old motorbikes. Also, we're reliably informed that it almost definitely does not feature an overweight Marlon Brando in a poorly-lit cave.

So, make sure you've armed yourself with what's left of the mince pies and Christmas chocs, settle-in and enjoy - it's going to be a belter.
