The maker of a documentary-style video about Domino's Pizza acted "naively" and "zealously" in a campaign against the fast food giant and should be forced to pay its legal costs in a battle to stop the footage being aired, the Supreme Court has found.

A legal fight erupted last Friday between the film's maker, 33-year-old Phoebe Stuart-Carberry, and Domino's Pizza after Ms Stuart-Carberry refused to hand over an "exclusive interview" she had filmed with a Sydney IT firm locked in an intellectual property dispute with the pizza chain.

The Supreme Court granted a temporary injunction last Friday to stop the footage being aired on the basis there was an arguable case of intimidation. It ordered Ms Stuart-Carberry to hand over a copy of the video to the court.
