Cotillard, who is pregnant with her second child, dressed her blossoming baby bump in a crimson one-shoulder Dior dress. The radiant free-flowing gown featured a single long sleeve and a modest knee-grazing slit and hinted subtly at the 41-year-old's changing silhouette beneath it. For the chilly November night, the Oscar winner styled her brown strands in fuss-free waves and opted for a low-key pink pout and slight smokey eye.
Beside her—just one week after making his solo red carpet debut since confirming his split from Angelina Jolie—Pitt, 52, looked every bit the leading man in a sharp navy suit with a matching overcoat and scarf draped artfully over his lapels.
A sweeping romantic thriller, Allied tells the story of an American intelligence officer (Pitt) who falls in love with a French Resistance fighter (played by Cotillard) while on a mission in North Africa during WWII.
