EXCLUSIVE: Melissa Leo is attached to star in the feature film Always On My Mind from writer/director Chris D’Arienzo (Rock of Ages). She’ll play the wife of an Alzheimer’s-stricken music legend. As the ailing rock star’s devoted wife, Leo realizes that her husband has been keeping a shocking secret throughout their long relationship. The aging rocker has not yet been cast.

The meaty role in this drama will have Leo playing rock icon Pete Carey’s loving wife Rosie, described as “a pillar of strength” as his health deteriorates. She cares for him even when the disease has him by the throat and he lets slip that he fathered a child with another woman. After an internal struggle and a lot of anger, she decides that it is important to reconnect Pete with his son. Pete’s role in the film is as intense as Rosie’s.

The indie project is being produced by Felipe Marino.

Leo is both an Oscar and Emmy winning actress (for The Fighter and Louie, respectively) and her credits include The Most Hated Woman in America, Snowden, HBO’s All The Way (portraying Lady Bird Johnson) and The Big Short.

She is repped by CAA and Untitled Entertainment.
