John Barrowman and David Bradley will return to their roles as the First Doctor and Captain Jack in the new event "Time Fracture"
The news was confirmed on the official twitter account for the Time Fracture event with a series of pictures featuring the two recording scenes.
"This is going to be something really special," Bradley said. "Anyone who sees the show who is not a Doctor Who fan when they go in, surely will be when they come out! It's going to be an amazing experience."
Barrowman added: "I wanted to get involved not only because I love storytelling and I love Captain Jack the character, but also because this introduces Jack to the next generation of Doctor Who fans.
"If you're coming to this – why not dress up as your favourite character? It's going to be like Comic Con but with a storyline! Create your character, get in there and enjoy the journey."
