"A new trailer for Doctor Who&amp;#039;s series opener &amp;#039;The Bells of St John&amp;#039; has been unveiled. The 30-second video features clips from the episode, which sees the full-time introduction of Jenna-Louise Coleman as new companion Clara Oswald.  The episode was teased with a prequel earlier today (March 23). The scene was penned by Steven Moffat and sees The Doctor in a park talking about his search for Clara with a young girl.  The BBC sci-fi series returns to screens next Saturday (March 30) for a run of eight new episodes ahead of the show&amp;#039;s 50th anniversary celebrations later this year. The first episode of the series has been described as a &amp;#039;modern-day urban thriller&amp;#039; by writer Steven Moffat and sees the Doctor and Clara face a threat lurking in the UK&amp;#039;s Wi-Fi network. A full trailer for the series was premiered by the BBC last week, as well as iconic posters for four of the new episodes.  Moffat confirmed that River Song will return and old enemies the Cybermen and the Ice Warriors will also feature in the new episodes.  &amp;#039;The Bells of St John&amp;#039; airs next Saturday at 6.15pm on BBC One.
