Doctor Who episode 478: The Invasion of Time – Part Five (4/3/1978)
Derek Deadman is no Kevin Lindsay. He whispers like an Ice Warrior and sounds like Ian Dury (cue laboured Ian Stor-y and the Potato Heads’ Hit Me With Your Swagger Stick joke). The Sontarans are generally a good choice for this though, having assessed Gallifrey’s military potential as far back as The Time Warrior and, with their endless clone army, being a more credibly formidable threat than the Cybermen, and a more thuggish contrast to the genteel Time Lords than the Daleks. This lot look suitably robust and solid as they march through the Capitol.
