An accounting miscalculation is being blamed for unpaid wages on the production of Run to Boston, which recently filmed in Ballarat.
Run to Boston tells the story of 1947 Boston Marathon winner Suh Yun-bok, the first Korean to win an international sporting event in his nation's independence from Japan in 1945.
It was filmed in Ballarat in mid-January, transforming Lydiard Street into the post-war Massachusetts capital, using signage, heritage vehicles and hundreds of extras.
Those extras have now contacted The Courier, some in personal and financial distress, to say they are still awaiting payment some five weeks after filming.
One saids she knew of "a heap of locals who haven't been paid," and that extras had been treated poorly by some of the assistant directors during the shoot.
Another extra said she had closed her small business for a week to take part in the production, and the failure to receive payment was causing her financial grief.
John Hipwell, the principal of Hipwell International Production Services, the company organising the production, says shortcomings in the preparation of accounting and the large numbers of extras used in filming had overwhelmed the accounts department, and that the team was working overtime to attempt to get payment to those owed outstanding wages.
He told The Courier he did not want to make excuses for the delay, and that ultimately he was responsible for making sure people were paid, and said he apologised profusely to thoise waiting.
Mr Hipwell said he would be providing a statement on the matter early next week after he had ensured everyone had been paid.
Adam Portelli, the Media, Entertainment and Arts Alliance's regional director for Victoria and Tasmania issued a statement confirming the union was also fielding complaints about the non-payment.
"Despite the fact that Road to Boston completed filming a month ago, we have been contacted by extras and crew who are yet to paid," Mr Portelli said.
"Depending on when they worked during the production, they were either not paid or only partially paid.
"We have recently contacted the production which committed to paying employees their outstanding wages and other entitlements. As of today, we have been advised by at least some members that this has not occurred."
The union said it had reports of regular unpaid overtime during the production.
"The fact that these workers have not been paid some or all of what's owed to them, weeks after this film concluded, is unacceptable.
"It's especially galling because Ballarat rolled out the red carpet for this production and many of the hundreds of extras were locals. In the same way that supermarket and hospitality workers deserve to be paid what they're entitled to and on time, so do entertainment industry workers."
The City of Ballarat told The Courier it had no outstanding accounts from Hipwell International Production Services Film production team.
