The Sin City beauty hit the London stage alongside Thandie Newton, singer/actress Neneh Cherry, Sting's producer wife Trudie Styler and British comedienne Meera Syal to stage A Memory, A Monologue, A Rant and A Prayer.
The show, made up of a series of short monologues, was aimed at raising awareness about women's rights and boosting donations to charities Women for Women International, V-Day and the Domestic Violence Intervention Project.
Speaking before the production, Dawson told the London Evening Standard newspaper, "One in three women are going to be raped, killed, beaten or abused in their lifetime and that's a huge number of women.
"The show is entertaining, thought-provoking and emotional. I've never been on the stage in London before and it's a great opportunity to get up there and do something I'm passionate about."
