8.25 Chepstow

Atlantis emerged from the green screens of a former Tesco cold-store in Chepstow - and did quite well for BBC1 last night. 5.6m viewers for what really should be a tea-time show, against 7.8m for the X-Factor's dubious jeopardy innovation of six-chairs-makes-for-more-tears.

Atlantis, born from Merlin, didn't quite outstrip its begetter, which scored 6.6m for its first episode - against 9.6m for the X-Factor - in 2008.

Strictly averaged 9.2m.

There are 12 more Atlantis stories to come. By the end, Jack Donnelly, as Jason, morphs into Steve Punt, of the Now Show...
