Its all change in the world ofDoctor Whoat the moment.

(Watch this get leaked to theSunas insider information.)

In a way, this would be going back toWhos roots in as-live television.

Since television production moved into the digital realm, live episodes of any drama are a rare beast.

But what would a liveDoctor Whoepisode look like, staged here and now?

Without one in the pipeline (that we know of), the rules are ours to set.

There are a couple of questions that immediately jump to mind.

Why would they do this at all?

What would a live episode actually look like?

What would the story be?

What would they need to do to get it to work?

To get a professionals point of view, I spoke to a freelance production coordinator.

The visual effects issue would be the biggest thing, she told me.

Even something like the TARDIS fading in how do you achieve that on screen with no post production work?

The proximity matters because actors would need to be able to get to them in real time.

When filming their first live episode in 2010, this was one of the many issues that faced theEastEnderscrew.

On one drive-round, the trip between studios was timed at 1 minute 16 seconds, if youre curious.

Overall, the whole endeavour took five months of planning and two weeks of rehearsals.

Shows likeEastEndersmanage because theyre not so far away from theatre productions themselves.

But a show likeDoctor Whois a different sort of beast altogether.

Locations change from story to story.

There are huge, expansive sets and lots of dangerous stunts.

Of course,Doctor Whois not a stranger to live productions.

Theres a lot of potential for things to go wrong with a live production.

Performers have been known to make gaffes in live broadcasts.

Think of how much more likely that is inDoctor Who, where theres a lot of technical jargon.

There could be a power cut to the studio, which would affect pretty much everything on the set.

This would be a good reason to film one of the rehearsal runs.

Even the sound could be affected at any time.

Basically, everything that can go wrong will go wrong.

If they were to do something like this, it would need to deliver on the promise ofDoctor Who.
