Now that Lego has moved into the movie tie in franchise dealio and seems to be doing pretty well out of it. What would you go for as a tie in theme that isn't beyond the reaches of practical achievability?
For me, I've always wanted a James Bond 007 theme. Villains secret bases, cool cars, Q's lab, Submarine HQ with M. Space station, helicoptors (little Nell?)and planes, luxury yacht, Casino. that sort of thing.
Bizarrely, I've always wanted a Lego zoo too. It's a childhood thing, Lego does cool animals and as of now there are plenty that could be used but there are no animals like lions, or tigers, or giraffes. horses could be repainted as zebras, polar bears cast in brown for grizzy bears, dogs painted as hyenas.
it's just something I always felt was missing from the city theme. they've done it in DUPLO but in minifig scale it'd rock.
The Hobbit and Lord of the rings LEGO would have been cool as an add on to the castle theme. Minus Tirith, Minus Morgul, The black gate, Lothlorien, Rivendell, Hobbiton, with the short leg pieces you've got hobbits and Dwarves, they could do a taller leg piece for elves and Sauron. Re-jig the Horntail dragon from Harry Potter and you've got Smaugor the fell beast. It'd be easy to come up with a Shelob and Troll. Even the watcher at the mines of Moria is achievable.
A UCS Oliphaunt would be incredibly cool.
For star wars I'd like a studio set. George lucas, cameraman, Rick McCallum, a bank of monitors, blue/green screen wall...... (I jest)
Annyhoo, just throwing this out there, NON star wars themes. Go wild.
