Last night’s opening ceremony, which was shown to the press corps via simulcast in the Debussy theater, was pure joy, especially if you speak French. French film and theater actor Edouard Baer emceed the event with ironic bonhomie and a piano player who accompanied him as he delivered a spoken-word-style love letter to cinema and to humanity at large. With Anna Karina, the actress from “Pierrot le fou,” (this year’s poster depicts a scene from that movie) watching him in the audience, he played short clips from the film and entertained the audience with quips.
