Gallery: filming the Burma special

You've watched the trailer, now head behind the scenes at the filming of this Sunday's very slightly delayed Christmas special, which airs this Sunday at 8:00pm on BBC Two.

If you've not already guessed - or missed last week's show - Part One of this epic challenge sees Jeremy, Richard, and James embarking on a voyage across Burma in lorries they've bought for not a lot of money off the internet. Why? To build a bridge over the River Kwai...

We have no idea if this particularly ambitious challenge will end in tears, or two tiers, but we can guarantee stunning scenery, much adversity, regular malfunction, and terrible shirts.

See you on Sunday. Or on iPlayer over the next few weeks.
