On April 20th, HBO will debut their latest original film, Mary and Martha, a tale of two mothers fighting to prevent the spread of malaria after they both lose sons to the disease. The film stars two-time Oscar® winner Hilary Swank (Million Dollar Baby) and Oscar® nominee Brenda Blethyn (Atonement) as the titular characters whose strong bond helps them enact change even as they are consumed by grief. Ahead of the premiere, HBO has released two trailers for the film, both of which are embedded below.

In addition to Swank and Blethyn, the cast also includes James Woods (Too Big to Fail), Frank Grillo (End of Watch) and Sam Claflin (Pirates of the Caribbean: Strange Tides).

Mary and Martha premieres Saturday, April 20th at 8PM on HBO.
