Hollywood is in its last hours to reach an agreement with the members of the Screen Actors Guild, or else the future of some of the upcoming movies and TV shows could have an unhappy ending.

SAG-AFTRA is preparing to strike if the union and the Alliance of Motion Picture and Television Producers, which represents Hollywood studios, do not reach an agreement by midnight (NBCUniversal, the parent company of TODAY. com, is in the Alliance).

«We’ve been at this for weeks with great hope that we can come to an equitable agreement,» SAG-AFTRA President Fran Drescher told TODAY of the negotiations. «However, we are not going to settle.»

Drescher’s comments come after more than 1,000 actors, including stars such as Jennifer Lawrence, Meryl Streep and Joaquin Phoenix, signed a letter to union leaders saying they are «prepared to strike.» according to deadline.

«This is not a time to meet in the middle, and it is not an exaggeration to say that the eyes of history are upon all of us,» the actors said in the letter, according to Deadline. «We ask you to push for all the changes we need and the protections we deserve and to make history by doing so.»

Actors are demanding higher salaries, more streaming waste, and protection against the misuse of artificial intelligence.

«This is the power of celebrity,» Marc Malkin, a senior editor at Variety, told TODAY. «We have great talent: the highest paid people in Hollywood. But they’re willing to go on strike and say, ‘No, we’re not going to budge.'»

SAG’s contract is set to expire at midnight, which could lead to the actors going on strike, along with the television and film writers, who authorized a strike nearly two months ago.

reported deadline most scripted TV series have already been shut down or stopped by the writers’ strike.

If the union and the studies do not reach an agreement, the work stoppage of the writers could worsen, which has stopped the production of series such as the fourth season of «Emily in Paris» and the final season of «Stranger Things».

Streaming platforms have been leaning towards foreign shows, while networks are replacing scripted series with game shows and reality shows during the writers’ strike.

If the actors attack, US series that have been able to continue filming abroad in the UK and Europe could also be shut down, according to Deadline.

As for movies, a strike could cause summer’s hottest movies like «Barbie,» «Oppenheimer» and «Mission Impossible» to be box-office hits, since the actors couldn’t promote the movies.

The future of movies during the last quarter of the year would also be uncertain, as a strike would cause the complete shutdown of feature film productions around the world.

reported deadline SAG and the alliance are considering extending negotiations to July 7 or later due to the upcoming holiday, but for now the deadline to reach an agreement remains midnight.
