Three of Hollywood's major unions are teaming up in the fight against film and music piracy.
Stolen DVDs are destroyed in Thailand
The Entertainment Industry Coalition for Free Trade is attempting to persuade policy-makers to get tough on copyright laws.
It is also targeting foreign countries with poor records on protecting copyrighted material.
The coalition is made up of the Directors Guild of America, Writers Guild of America and the International Association of Theatrical Employees.
The group will hold a launch in event in Los Angeles on Thursday.
Motion Picture Association of America (MPA) chief executive Jack Valenti is due to appear at the seminar.
He has been outspoken about the effects of digital piracy - downloading music and film from the internet - is having on the industry.
'Menace of piracy'
He sees the problem as one of the biggest facing the business, quoting figures of 400,000 to 600,000 films being illegally downloaded a day.
Mr Valenti has been trying to raise public awareness of the "menace" of film piracy.
His concern is that the film industry will suffer the same fate as the music industry which has blamed falling profits on illegal music swap websites.
The coalition is also seeking to use trade negotiations to lay the groundwork for strong copyright laws across the world.
The MPA is already working with Indian film studios to stem the flood of pirate DVDs flooding the market there.
Thailand has confiscated and destroyed millions of illegal DVDs but it continues to struggle against those determined to sell cheap music and films.
