10 Times Doctor Who Made Obvious Mistakes

When Day of the Daleks aired in January 1972, it had been five years since the last Dalek story, The Evil of the Daleks. In an age where repeat screenings were rare, and VHS, DVD, Blu-ray, and streaming services were non-existent, it's no surprise that voice actors Oliver Gilbert and Peter Messaline struggled to convincingly replicate the voices for this classic Third Doctor serial.

However, it's not really Gilbert or Messaline's fault, as the original Dalek voice actors were all still working when Day of the Daleks went into production. It's unclear why producer Barry Letts or director Paul Bernard didn't hire old pros like Roy Skelton, David Graham, or Peter Hawkins to reprise their roles, but on reflection, that's precisely what they should've done.

This mistake led to the Daleks sounding quite shrill and unthreatening, made worse by the small number of Daleks revealed onscreen. But on the plus side, Day of the Daleks is a classic in spite of this casting mistake and paltry Dalek count. It's essentially Terminator with Daleks, and both Terrance Dicks' novelisation and the 2011 CGI update of the story shows off its full glory.

Predictably, Nicholas Briggs stepped in to record the new Dalek voices for the 2011 update. Who else?
