Some TV and cinema viewers will have the opportunity to get a glimpse of the Twelfth Doctor, Peter Capaldi, in the new Doctor Who Experience TV advert. The advert gives fans and families a sneak preview of some of the adventure visitors will go on. Spoiler Alert - we haven't given too much away but you will see some of the interactive adventure.

A true gentleman, his personality was as big and warm as his voice. We’ll miss him very much.

In the distant past, the land that would be India played host to a war between ancient aliens, whose cross-temporal battles contributed to the country's rich myths and legends. Kali, oldest and deadliest of these creatures, was thought defeated long, long ago; her body scattered throughout time to prevent her return. But her psychic essence could not be killed... nor her millennia-long quest for vengeance.

Now, in the 23rd Century, she is on the brink of resurrection. And with India at the forefront of human spaceflight, it's not only Earth that falls to her predations if she succeeds – but the whole cosmos!

In a race against time, and across it, the Doctor and Clara must gather secrets, intelligence and allies from across India's past, present and future – if they are to survive... THE SWORDS OF KALI!
