Everyone's favourite reluctant traveller is back in the departure lounge. But this time Ricky Gervais and Stephen Merchant (The Office, Extras) are sending Karl Pilkington around the world with a list of the ultimate things to do before you die.

Armed with this definitive bucket list, Karl will be dispatched to far flung corners of the world to swim with dolphins, travel Route 66 and stay on a private desert island, in an attempt to prove whether these so called 'things to do before you die' really are what they're cracked up to be.

After seeing the Seven Wonders, Karl's not exactly eager to travel again, so he's only agreed to do another series if the rules change. Karl wants to choose where he goes and what he does from the Bucket List.

Ricky and Steve are both happy to go along with Karl's wishes to get him through the departure gates. Once Karl's back on the road, they'll be back to their old tricks though, throwing in unwelcome surprises for Karl along the way to make sure he's always pushed out of his comfort zone...
