There's a distinct Edwardian meme floating around; obviously LEGO themselves could be part of it through what figurines they produce. However witness the recent Doctor Who stylings and Sherlock Holmes reboots among others.

This dude looks pretty serious, and I'm told he's a General!

The Influence of 'Potter makes itself felt

Before the happy day when some gen-yoo-ine actual Harry Potter Lego arrived, there was nevertheless a pressing need to express some Dementor related scenarios. So, something got done.

This is put together from some Star Wars lego, with You-Know-Who* getting the "Battle Damage Darth Vader" head.

I particularly like the re-purposing of the Ewok flying machine stand ...

Scene of great ersatz drama.

'Droids, 'Droids, 'Droids

The 'Droids seemed to be most apt for creating some mini-figurine "Island of Dr. Moreau" - those parts do go together in quite a few different ways...
Here are a few.

The battle 'Droids quite often develop Shiva-like attributes...

I think this is essentially a very complicated light sabre.
Health and safety violations abound, such needing to hold them by the blade.

This guy is either getting awesome 'phone reception,
or can hear a pin drop from orbit.

Not to be out-done, this was the nadir of the arms race.

Relatively tame

Tuns out this idea didn't have legs.

An attempt at even greater fidelity to the films.

You can do just about anything for the heads of these things.

For a while, there was a strong emphasis on greater size for everything,
leading some very serious limb / gun inflation. 

Remote working *will* be the future

There are quite a few like these, but this one is the epitome.

Pushing the available figurines and seating space to the limits results in this.

It has been determined that in the future public transport will be crowded.

There was a flurry of ideas like this at one point, which seems to have died down. There were ships and speeders of various sizes with largely one or two passengers/ pilots. This one is an extreme example.
