Wednesday was International Women’s Day — but it was also a two-show day for most of Broadway, so not many women in the New York theater industry — many of whom work onstage and backstage — could partake in the day’s strike action, A Day Without a Woman. But theater types still found ways to participate.

Case in point: The Broadway cast of “Hamilton.” The play’s actors opted to donate their salaries from the Wednesday evening performance to Dress for Success, a charity that supports women entering the workforce. Javier Muñoz, who plays the title role in the megahit musical, tweeted a photo of the leaflet that was inserted into programs that evening.

Female crew members, many wearing red, emerged for the curtain call, as the cast declared, “Happy International Women’s Day,” according to theatergoers who were in the audience that night.

There were other ways for Broadway workers to show their support as well. Broadway Strong, an activist group formed by members of the theater community, organized a rally on March 8 at 5:30 p.m., between Broadway’s 2 p.m. and 8 p.m. shows, which allowed actors and backstage crew to participate.

The theater district wasn’t the only division of the entertainment industry to recognize International Women’s Day. Companies across all sectors of showbiz acknowledged the day.
