The laid-back star, who plays Haymitch Abernathy in the trilogy, joined his costars Josh Hutcherson, Jennifer Lawrence, Liam Hemsworth and director Francis Lawrence at a photocall in Paris before the night’s big premiere. Hutcherson, Hemsworth and the director wore black pants, nice shoes and either a button-up or a blazer.

Katniss Everdeen herself, Lawrence, wore a Dior Haute Couture chiffon dress and belt with lace booties by the brand (so very French). And then Harrelson wore flannel PJ pants and decorative socks.
