Conventional wisdom says there are two ways to make a shark attack movie. You can set it at sea, where most sharks live, and try to use character, plot, compelling action, and maybe over-the-top devourings to make your story feel unique. Or you can lure in viewers by putting sharks somewhere no one expects sharks — flying through the air and landing all over Los Angeles! Roaming the streets of downtown New Orleans! Swimming through the snow at a ski resort! Bursting out of the ground in the jungle! Most filmmakers who choose the latter path have to abandon any sense of reality and embrace absurdism. Netflix’s French thriller Under Paris, from Hitman director Xavier Gens, is a bold attempt to have it all.
