Doctor Who 8.02 "Into The Dalek" Spoiler-Free Preview

Episode two is, in many ways, very different from episode one - it's a futuristic, space-set adventure featuring the return of the Doctor's greatest enemies. It feels like what it (presumably) is: a Phil Ford story with a healthy sprinkling of Steven Moffat.

You'll be reminded of "Journey To The Centre Of The TARDIS" and "Dalek". And "Let's Kill Hitler".

There's one scene which is right out of the original Star Wars . Right out of it.

The word "Silence" is used.

One of the soldiers has a great name.

It starts with a spectacular space battle that showcases just how tremendous the show's special effects routinely now are.

A Dalek says the word "Doctor", though not for the reason you'd expect.

There's a reference to a very, very old story in the show's history.

A good man goes to war. But then again, is he a good man?

The line "Resistance is futile" are heard. Yes, really!

There's one particularly spectacular explosion.

Great line: "You'd starve to death trying to find the light switch."

Ow, that's a heck of a slap!

Clara is a fast mover. In every sense.

What goes down must come up.

There's a sort of reference to a 1966 movie - not surprising, when you realise what the plot's about.

Some of the things the Doctor says and does will make you gasp.

It's a dark, claustrophobic, hard-edged story that's a long way from the lightness and brightness of much of the Matt Smith era. If you liked "Deep Breath" you'll probably like this one - if you didn't care for "Deep Breath" you may not take this one to your heart either.

"Into The Dalek" airs on BBC One at 7.30pm on Saturday 30 August.
