The 'Total Film' article below simplified the story a little - well, it is confusing. One of the guys who stole the videos has been convicted and sentenced to 12 months supervision and counselling. According to NZ's film industry magazine Onfilm, one of the others (the 35-year-old company director) also accused of stealing scripts, swords, and VHS tapes has denied it. Furthermore, he's elected for trial by jury. According to Onfilm, Peter Jackson wrote to the judge asking that the name suppression be lifted. However Judge Nicola Mathers said that publishing his identity could lead to publicity out of proportion to the offence. Well, he'd be all over the Net, so that's certainly true.
The accused is currently overseas.
There was a third person involved in this; he was accused of money laundering. I have no updates on him.
