We certainly use the term Wellywood when referring to the film industry here and PJ is just about a god locally. But that sign idea is just so tacky. And a lot of the film work (outside of Weta studios) has moved to Auckland already.

By the way, Jackson was one of the first to put S&SF genre stuff out there but only one of them. Cloud 9 (the Tribe) and Renaissance Pacific (Hercules & Xena) were in there too. BUT it took overseas recognition for any of them before local support picked up. I suspect the same attitudes are in place over your way.
