Paul McGann has announced that production has begun on a sequel to The Five(ish) Doctors Reboot. A report by The Cambridge News says:
Appearing at the final event of the Cambridge Union Society’s Easter term, McGann also revealed that production had begun on a sequel to The Five(Ish) Doctors Reboot – the acclaimed comedy that saw writer-director Peter Davison teaming up with fellow ex-Time Lords McGann, Colin Baker and Sylvester McCoy to try to secure a place in the Doctor Who 50th anniversary special.Great news, eh? Makes me wonder if we're going to be getting another multi-Doctor special for the Tenth Anniversary of the show revival in Spring 2015.
