It was followed by a Q&A with Elisabeth Sladen and Katy Manning, plus script editor Gary Russell, SJA writer Joseph Lidster and branding manager Edward Russell. Plenty of discussion about the series, not to mention the influence of Russell T Davies. At the end of the panel both Katy and Lis paid tribute to Barry Letts, who was responsible for the creation of both of their characters alongside Terrance Dicks (and Robert Holmes - who wrote both their first stories, they forgot that!).
A sample of photos, there are some more on Facebook!
