Only just seen your posts Iain - cheers for such enthusiasm. I'm currently trying to get the green light for a second series of IJ, but it comes down to budgets right now. Discovery were v pleased with the ratings both here and abroad so hopefully it will happen. In terms of filming location stuff, we do it a chunk at a time, so for trucks the whole thing was filmed out in north Sweden. For the explosives we filmed one bit in Sweden, then one bit in Romania, then another bit elsewhere. These are all separate filming trips. Filming takes bloody weeks and weeks.
Am currently filming the new series of Fifth Gear, which will go out on the screens in early June I think.
