The Film Commission's talking up the benefits of multi-million dollar subsidies for the upcoming Avatar movies.

Newstalk ZB has revealed the next four movies have so far received $140 million in production grants.

Film Commission Chair Dame Kerry Prendergast told Mike Hosking it's provided 20,000 jobs in the past year.

She says they've just had a report done which shows for every dollar spent on the screen sector in New Zealand, there's a $6.15 return.
