US actors union Sag-Aftra has ratified its contract with Hollywood studios, a month after a tentative deal was agreed.
Although actors have already returned to work, the ratification formally ends the strike which began on 14 July.
The Screen Actors Guild (SAG) said 78% of members voted in favour of the multi-year contract. Turnout was 38%.
Actors won $1bn (£790m) in new compensation and benefits as well as protections from studios' use of AI.
Union president Fran Drescher said: "This is a golden age for Sag-Aftra, and our union has never been more powerful."
The Alliance of Motion Picture and Television Producers (AMPTP), which represents studios including Netflix and Walt Disney, said "the industry and the jobs it supports will be able to return in full force" now the three-year contract had been ratified.
A tentative deal between Sag-Aftra and Hollywood studios was agreed in November, putting an end to the 118-day strike that paralysed the entertainment industry and disrupted numerous major films and TV shows.
The deal includes, among other things:
- An immediate 11% pay increase for background actors
- A $40m (£32m) residual bonus for actors who work on series or films released via streaming services that become successful
- AI protections that require "informed consent and fair compensation" for any living or dead performer
- New make-up and hairstyling requirements, including experts for performers with diverse hair textures and skin types
- A first-ever requirement to hire intimacy co-ordinators on set for scenes involving sex and nudity
Duncan Crabtree-Ireland, the union's chief negotiator, said that although the deal was not "perfect", it had a "lot of really important gains".
He added that it was a deal he was "really proud of".
Although Hollywood's star actors earn millions of dollars, many lesser-known performers often struggle to get by, particularly amid rising inflation and industry changes.
The 118-day shutdown was the longest in the union's 90-year history.
The combination of the actors' and writers' strikes is estimated to have cost the California economy more than $6.5bn (£5.26m), according to trade publication Deadline.
In November, high-profile actors including Zac Efron, Jamie Lee Curtis and Octavia Spencer were among those welcoming the deal.
