Ellex has provided pro bono legal services for the production of the 2022 documentary film Sisters in Longing, directed by Elita Klavina.
According to Ellex, "the film features women who are bonded by their pain, longing, and their current residence – a semi-open prison for women. While staging Anton Chekhov’s play, Three Sisters, together with professional actors, imprisoned women reveal their harrowing life stories, dreams, and the longing for a decent life outside the prison walls."
