Apple TV+ put the cast of 'Severance,' including Adan Scott and Patricia Arquette, in a glass box at Grand Central Station to promote Season 2.

The pop-up began when a large glass box appeared in Grand Central's Vanderbilt Hall, containing a replica of the four-seated desk from Lumon's Macrodata Refinement department. Hired actors playing Lumon employees sat at their desks, doing Lumon things (by which I mean, sorting numbers while not having a clue what said numbers mean).
