They want our car in a movie!!!!!!!

[Fantome]

Hi Everyone
A guy called at our home today looking for cars to be in an upcoming movie some of which will be filmed in Dubbo. The guy seemed genuine and answered all of our questions easily. He had a business card which had the head office number at Fox Studios. We rang and all seemed above board and a check of the NSW Film and Television Office website showed the movie listed on the upcoming productions with correct shooting dates and production company.
Has anybody had any experience with something like this? What to look for/check? Could this be a scam?
