The pair embraced as Phoenix reacted with legitimate surprise after being named the winner of the coveted award.
Mara was a vision in white, rocking an angelic, bead-embellished Dior gown with three-quart sleeves and a collar, while Phoenix rocked a crisp tuxedo that he paired with black converse sneakers.
The actor apologized for his less-than-formal footwear as he took to the stage to accept his award from actress and Cannes jury member Jessica Chastain, explaining that the win was "totally unexpected."
