Jon Voight, Mel Gibson and Sylvester Stallone will be Trump's eyes and ears in Hollywood

US President-elect Donald Trump has appointed three special envoys who he says will help promote business in Hollywood.

Actors Jon Voight, Mel Gibson and Sylvester Stallone have been chosen to serve as Trump's "eyes and ears" as they help improve the US film industry, which he has called a "great but very troubled place".

"They will serve as my special messengers with the goal of bringing Hollywood, which has lost a lot of business to foreign countries over the past four years, back - bigger, better and stronger than ever!" wrote Trump on Truth Social. "This will once again be, like the United States of America itself, the Golden Age of Hollywood!" he added.

All three actors have publicly expressed their support for Trump.

In a video address last fall, Voight called voting for Trump's political opponents - Kamala Harris and Tim Waltz - "the lowest and most despicable choice you could trust your life, your children's lives, to."

"They will destroy the American dream. They are corrupt," he said.

Stallone, while introducing Trump at a gala dinner at Trump's Mar-a-Lago estate in November, compared him to the nation's forefather, George Washington. | BGNES, AFP
