heat went to the big Doctor Who launch last night, and we saw the first two episodes and we have to say, contrary to the thoughts of some of the show's geekiest fans, Catherine Tate is brilliant in it, adding a whole new layer of humour, humanity and down-to-earth gutsiness to proceedings. The whole event was as exciting as ever, with those new episodes screened in full, plus thrilling trailer for the rest of the series AND a questions-and-answer session afterwards with David Tennant, his new companion Catherine Tate and writer/exec producer Russell T Davies. The first ep (previewed in the current issue of heat) is a fab re-introduction to Tate's character who first appeared in the Christmas special two years ago. The scene in which they first clap eyes on each other is priceless. But the second episode is a classic – set in Pompeii, the day before Vesuvius is due to erupt and it's one of the most spectacular Who stories ever. As well as being funny and moving. Oh, and Tate gets even better, showing she can cry with the best of 'em. As for the rest of the series, we got a glimpse of Billie Piper toting a big weapon. Doesn't get much better than that. We also asked Russell T Davies about the controversial new early timeslot of 6.20pm, which we feel doesn't give us enough time to get back from the shops on a Saturday, and he made his displeasure clear, but also said the BBC had indicated to him that, midway through the 13-part series, Who will get its old, later slot back. Yay! Don't miss the first episode this Saturday, BBC1, 6.20pm.
