Julia Roberts and Carrie-Anne Moss have signed on to star in the ensemble drama, Fireflies in the Garden for Senator Entertainment; Emily Watson and Ryan Reynolds are in negotiations to join the cast.

The film marks the German company's first U.S. production; it's written by Dennis Lee, who will make his directorial debut on the project. The story is loosely based on Lee's life and explores the complexities of love and commitment in a family torn apart when faced with an unexpected tragedy, says The Hollywood Reporter.

Shooting on Fireflies in the Garden is scheduled to begin in March in Austin.
