Filming is underway in Australia on new Sky fantasy-adventure-comedy film, The Portable Door.

The film stars Christoph Waltz, Sam Neill, Patrick Gibson, Miranda Otto and Rachel House.

It’s being made by The Jim Henson Company for Sky, and is based on the books by Tom Holt.

The story follows Paul Carpenter and Sophie Pettingel, the lowly, put-upon interns who begin working at the mysterious London firm J.W. Wells & Co. and become steadily aware that their employers are anything but conventional.

Charismatic villains Humphrey Wells (Waltz), the CEO of the company, and middle manager Dennis Tanner (Neill) are disrupting the world of magic by bringing modern corporate strategy to ancient magical practices, and Paul and Sophie discover the true agenda of the vast corporation where they work.
