The Perfect Family & Albert Nobbs - Both excellent explorations of sexual orientation/gender roles.
And both with outstanding female leads.
The Perfect Family
When tightly wound suburbanite Eileen Cleary is nominated for her church's Catholic Woman of the Year award, she pushes aside inconvenient truths, including an alcoholic son, a gay daughter and a philandering son, in favor of a "perfect" family.
Having for decades disguised herself as a man while working as a butler in a posh 19th-century Dublin hotel, a woman calling herself Albert Nobbs reconsiders her charade when a handsome painter arrives on the scene.
