New Doctor Who star Peter Capaldi is set to travel around the world - without the help of his Tardis - as he and co-star Jenna Coleman go on a tour to promote the show.
The pair will visit five continents in the space of just 12 days, calling in at seven cities, ahead of the launch of the actor's first series as The Doctor.
The tour will begin in the UK, visiting Cardiff on August 7, before heading to London and ending up in Rio de Janeiro in Brazil on August 19.
Along the way, the Sci-Fi starswill call in to South Korea, Australia, the US and Mexico.
The pair will also be joined by the programme's executive producer Steven Moffat for the publicity and fan events.
Fans were treated to a sneak peek of Capaldi in the role when he became the latest regeneration of The Doctor at Christmas.
Since then, The Thick of It star has been working on his first full series with Coleman who returns as his assistant Clara.
It is the largest promotional tour undertaken for the show which is broadcast around the world and still on a high after its 50th anniversary celebrations last year.
A special episode, The Day of the Doctor, was broadcast in 98 countries simultaneously and was seen in more than 1,500 cinemas.
It's fantastic that so many people across the world love Doctor Who. After eight months solid filming deep in the world of monsters, Jenna and I are thrilled to be heading for the planet of fans.
The new Doctor Who series, which includes guest roles from Frank Skinner, Ben Miller and Keeley Hawes, will be screened from August.
