Not how he got away with the questionable zombie stunt (see below), but he does explain many other tricks on the Channel 4 micro-site. I’d like even MORE explanations – but it’s a good start. I think some of the highlights of the past series have been the “reveals”, e.g. when replaying the speech he gave to (Bash the) Pegg that made him think he’d always wanted a BMX, and not the leather jacket he’d previously written down. No sign of the BMX on Dr Who though.
