Sadly, these photos are NOT of the PR stunt that Severance did for its new season; these are from a Sirius XM chat. But Mashable wrote a piece about how, for over an hour, the cast showed up in character to enact a day at Lumon inside a plexiglass box. Apparently the box was soundproof, or else they spent an hour merely mouthing to each other, because no one could hear what was said. But that is an extremely funny improv exercise, albeit one I’m sure they’re hoping they don’t have to bring with them on a multi-city tour.
