May 12 (Reuters) - A coalition of American film industry unions and guilds, joined by

veteran actor Jon Voight, has asked U.S. President Donald Trump to consider implementing tax

incentives in his push to promote domestic film productions, according to a letter seen by

Reuters on Monday.

Along with Voight, the letter was signed by Sylvester Stallone and Teamsters union general

president Sean O'Brien, among others. They call for Trump to support the inclusion of three

film-friendly tax measures in a reconciliation package being drafted in Congress.

Voight and Stallone were also appointed by Trump as special ambassadors to Hollywood to

strengthen the industry and bring filmmaking back to the country.

"Returning more production to the United States will require a national approach and

broad-based policy solutions, including those we propose below as well as longer term

initiatives such as implementing a federal film and television tax incentive," the letter read.

Major media companies, including Walt Disney ( DIS ), Netflix ( NFLX ) and Universal

Pictures, film overseas in countries such as Canada and Britain as governments around

the world introduce credits and rebates to attract film productions.

Trump threw the entertainment industry into a flux earlier this month when he announced a

100% tariff on foreign-made movies, saying the American movie industry was dying a "very fast

death" due to the incentives that other countries were offering.

The move left a lot of questions unanswered, such as when the duties would be implemented

and how they would be enforced - as different components of a film are made in different

countries and then assembled through post-production.

Trump's tariff pronouncement followed his meeting with Voight along with other executives

and advisers to mull a range of ideas to to revive domestic film and TV production, including

federal tax incentives.
