The screening will mark the start of the shows world tour, and will be fans’ first chance to see Peter Capaldi as the Twelfth Doctor, alongside Jenna Coleman as on-screen companion Clara, in episode one of the new series, Deep Breath.
The stars will be attending the lunchtime St David’s Hall red carpet event, together with lead writer and producer Steven Moffat.
Tickets will be available to the public from St David’s Hall Box Office from Monday 7 July.
BBC Wales Director Rhodri Talfan Davies says:
Doctor Who is getting even bigger and even better - and it's a real thrill that the show's fans here in Wales will be the very first to see the new Doctor at this very special premiere screening. Doctor Who has been made in Wales for almost ten years - and we're so proud of its worldwide success.The event is held in association with BFI Sci-Fi: Days of Fear and Wonder, the full programme for which will be announced later this month.
