Meryl Streep Protesters Disrupt Big Premiere

10/7/2015 10:38 AM PDT

A group of women -- more than a baker's dozen -- torpedoed the London premiere of Meryl Streep's new movie over women's rights issues ... which is ironic since Streep has been one of their champions.

It's unclear if Streep was on the red carpet yet Wednesday when the protesters laid their bodies on the ground -- showing their outrage for Parliament's decision to cut funding for domestic violence services.

The women -- part of a group called Sisters Uncut with a hashtag that reads #deadwomencantvote -- never said they have a problem with Streep or her movie, "Suffragette." The flick is about a group of women in England who championed the women's right to vote movement.

It's unclear if the protesters have issues with the film, or just used the venue to piss on Parliament.
