Aint it Cool have the scoop on this one, via The Man Who Japed. The tip-off came via the Sydney Herald that an overnight shoot would be taking place in Federal Park on Friday 29th of February.

The set was pretty cool. They had sealed off a fairly large section of the park and done it up as a carnival with lots of bright lights, some rides and a Ferris Wheel and various attractions. There were a lot of extras milling around in typical carnival attire such as mimes, clowns etc.

We saw someone who looked like Will.i.am from the Black Eyes Peas wearing a purple jacket and sporting an afro walking around the carnival set and conferring with the director, but what I found most interesting was the set dressing of the sideshow attraction. There was one that had a picture of a man with a beard in a top hat called Dr Freak advertising his freak show with a woman called ‘Elastina’ who I assume is going to be a mutant. There was also a three headed baby. It’ll be interesting to see how this ties in to the film.

In this first image you can see the references to Dr Freak and the three headed baby on the posters to the left, and the Elastina poster can be spotted in the third picture just sticking out from behind the ticket booth.
