Complicated sibling relationships are the basis of Dustin Guy Defa’s new film The Adults. The film depicts the emotional journey of three siblings played by Michael Cera, Hannah Gross, and Sophia Lillis, reuniting in their Mother’s death, a scenario that, while rife with potential conflict, also presents an opportunity for reconnection, understanding, and healing. As Defa portrays, such a reunion can cause the distance that has grown between siblings over time to become painfully real.
