Doctor Who on World Tour With New Star Peter Capaldi

Fans get sneak peek of new series

British science fiction show Doctor Who is celebrating its 51th anniversary, 34th season, and the arrival of a new doctor with a seven-city world tour spanning five continents.

The tour kicked off last week in Cardiff, Wales, the show’s home since its 2005 revival and London before making a stop in Seoul, South Korea on the weekend, and arrives in Sydney, Australia on Tuesday before continuing on to New York (Aug. 14), Mexico City (Aug. 16) and Rio de Janeiro, Brazil (Aug. 18).

Peter Capaldi, the new doctor and the 12th incarnation of the Tardis-travelling hero, on-screen companion Jenna Coleman and lead writer/executive producer Steven Moffat are taking part in the world tour, attending fan events and talking up the series to press. The tour also features an advance screening of the first episode of the new Doctor Who series, as well as a question-and-answer session with fans.

The new Doctor Who series is scheduled to premiere in the U.K. on Aug. 23 and will be available at 8 p.m. ET on the same day on BBC America. Doctor Who superfan and Nerdist podcast host Chris Hardwick will present before and after shows on BBC America.

The new episode, called Deep Breath, is set in Victorian London, where the doctor finds a dinosaur rampaging in the Thames River, according to a preview on the BBC website.
