One of the longest labor crises in Hollywood history is finally coming to an end. SAG-AFTRA, the union representing tens of thousands of actors, reached a tentative deal for a new contract with entertainment companies on Wednesday, clearing the way for the $134 billion American movie and television business to swing back into motion. Hollywood's assembly lines have been at a near-standstill since May because of a pair of strikes by writers and actors, resulting in financial pain for studios and for many of the two million Americans -- makeup artists, set builders, location scouts, chauffeurs, casting directors -- who work in jobs directly or indirectly related to making TV shows and films. Upset about streaming-service pay and fearful of fast-developing artificial intelligence technology, actors joined screenwriters on picket lines in July. The writers had walked out in May over similar concerns.
