Cadillac kicked off Oscar week with its annual cocktail party to celebrate the 90th Academy Awards. Held at Hollywood’s iconic Chateau Marmont, the exclusive event brought together some of the industry’s top insiders in addition to Oscar nominees Allison Janney (I, Tonya), Martin McDonagh (Three Billboards Outside Ebbing, Missouri), Bryan Fogel (Icarus), Benj Pasek (The Greatest Showman) and Katja Benrath (Watu Wote: All of Us), along with Tiffany Haddish, Sarah Silverman, Joel McHale, Dan Stevens, Elizabeth Perkins, Angela Basset, Aisha Tyler, Kathryn Hahn, Missi Pyle, Will Arnett, Mamie Gummer and more. Allison Janney discussed “taking a bit of a risk” with her Oscar dress this year, calling her choice “dramatic.” Tiffany Haddish teased that her yet-to-be-announced Oscar co-presenter is someone she’s wanted to work with for a long time and knows the Oscars will kick off their friendship. Joel McHale joked that the only way he’ll be at the Oscars is if Jimmy Kimmel makes him his plus 1. Cadillac is a proud sponsor of the Oscars for the fifth consecutive year and will unveil three new ad spots during the Academy Awards telecast. The spots focus on performance, technology, and the future of Cadillac vehicles.
