Upon first viewing, I definitely thought this show-stopping scene was created with CGI. Very impressed it’s all done using practical effects!
Vulture has the scoop:
Stylish, strange, and serpentine, FX’s Legion is in no way a conventional superhero show, despite being based on a character from Marvel Comics’ spandex-clad X-Men mythology. That said, it does retain one trope from its comic-book origins: superpowers. Protagonist David Haller (Dan Stevens) has a set of mysterious metahuman abilities, one of which is the capacity to move objects with his mind. That particular trait comes into stunning display in tonight’s pilot episode when a stressed-out David inadvertently causes the drawers and cabinets of his kitchen to fly open and eject all of their contents in slow motion. Watching the scene, you would be forgiven for thinking those swirling objects were spun with CGI and tossed around via ones and zeroes. But you would be wrong — astoundingly enough, the kitchen scene was done with practical effects.
