This Science-fiction series starred Christopher Eccelston as The Ninth Doctor, alongside Billie Piper as companion Rose Tyler.
When the revival aired in 2005, it was a big hit for the BBC; bringing in an average viewing rating of 8.08 million.
During the Q&A at Dragon Con in September 2021. The actor was asked about why he left the series (video timecode 2:51); according to Christopher Eccelston, situations were not going so great behind-the-scenes:
“I left because my relationship with [showrunner] Russell T Davies, [producers] Julie Gardner and Phil Collinson completely broke down during the shooting of the first series. I think it’s fair to say… that the first series, nobody knows what they’re doing, and the politics are raging. The shooting of the first series was a nightmare.”Christopher Eccleston – Dragon Con 2021
Eccleston left the show after only one season. However, negative responses and news coverage spread fast.
“In the UK, they never talk about the positives,” reflects Eccleston. “When I left, all they wanted to talk about was why I left. They never wanted to talk about the fact that I did 13 episodes. You know, we have a tradition of the gutter press in the UK, so I had to deal with them.”Christopher Eccleston – via Den of Geek

“I’ve never been a fan of multi-Doctor stories. When I worked on the series, I had really strong ideas about what works and what doesn’t, and I always think that multi-Doctor stories are a bit of a cash-in, and a bit of exploitation.”Christopher Eccleston – Australian Convention Supernova
