Kim Dotcom: Caught in the Web will make its Kiwi debut at the New Zealand International Film Festival.

Budding New Zealand film star Kim Dotcom is days away from the release of a documentary about his battle with Hollywood.

The makers of Kim Dotcom: Caught in the Web have released a trailer for their documentary, ahead of its premiere at the South By Southwest Festival next week.

Dotcom himself would be unlikely to attend the screening in the United States, as he remains wanted there for copyright infringements relating to his former website Mega Upload.

SUPPLIED Kiwi-made documentary Kim Dotcom: Caught in the Web is set to debut at Texas' South By South West Film Festival in March.

University of Auckland film and media professor Annie Goldson​ directed the documentary.

It was made independently, with just over $800,000 of investment from the New Zealand Film Commission.

CHRIS MCKEEN/STUFF An extradition order against Kim Dotcom was upheld by an Auckland court.

The film took three years to produce. It has been marketed as the story of "the most wanted man online".

New Zealand Film Commission chief executive Dave Gibson said Goldson​'s directing was "uncompromising".

"Her academic background and long-term commitment to documenting the complex space between the personal and political made her the perfect person to tackle a film about the internet, piracy, ownership and privacy," he said.

Dotcom had described his unusual life ironically as "like a Holywood script". In 2012 Dotcom's Auckland mansion was raided by New Zealand police and the United States' FBI.

His former website was accused of sharing pirated films and other content, costing copyright holders – including Hollywood film studios - more than US$500 million (NZ$696 million).

He was arrested in January 2012 after the mansion raid, yet he remains in New Zealand fighting extradition orders in the courts.

The just released trailer showed documentary makers talking with journalists, Dotcom and Hollywood representatives.

The 108-minute film was due to premiere on March 13 in Austin, Texas.
