Is there a better way to prove the virtue of the cinematic experience than to get 5,000 people on their feet giving a film a standing ovation? Cannes Film Festival chief Thierry Fremaux did just that on the opening night of his 14th Lumière Film Festival in Lyon with Louis Garrel’s romantic comedy “The Innocent.” The movie played in the jam-packed Halle Tony Garnier before a star-studded crowd, including Garrel and his cast, Noémie Merlant and Roschdy Zem, as well as Sebastián Lelio, Costa Gavras, Leila Bekhti, Marina Fois, Lee Chang-dong, Nicole Garcia, Sabine Azema and Damien Bonnard.
