Doctor Who: Drama shows how show nearly did not make it

A drama, recreating the behind the scenes action on the first ever Doctor Who, is being aired days before the show's 50th anniversary.

An Adventure in Space and Time charts the struggles Doctor Who writers had trying to get the show off the ground.

David Bradley plays the first Doctor, William Hartnell, and tells BBC Breakfast about his research into the role.

You can watch An Adventure In Space And Time on BBC Two at 21:00 GMT on Thursday, or watch again on the iPlayer.
