BERLIN – The press conferences and red carpet appearances never stop at the 66th Berlinale, the Berlin International Film Festival. The cast and crew of Hail, Caesar!, the opening-night film, walked the carpet. While the Coen brothers seemed a bit embarrassed, George and Amal Clooney couldn’t have looked more at ease. Human-rights lawyer Amal Clooney stole the show with a glittery gown and a glamorous look that rivaled any of the actresses. Channing Tatum, Josh Brolin and Tilda Swinton also shone in their black-tie finery.
